DEFINITION BERA
Alternative Names :
Evoked auditory potentials; BAEP - brainstem auditory evoked potentials; Evoked response audiometry
Definition :
The brainstem auditory evoked response (BAER) test measures brain wave activity that occurs in response to clicks or certain tones.
How the Test is Performed :
You lie on a reclining chair or bed and remain still. Electrodes are placed on your scalp and on each earlobe. The earphones give off a brief click or tone. The electrodes pick up the brain's responses to these sounds and record them.
How to Prepare for the Test :
You may be asked to wash your hair the night before the test.
How the Test Will Feel :
There is little discomfort.
Why the Test is Performed :
The test is performed to help diagnose nervous system abnormalities and hearing losses (especially in low birth weight newborns), and to assess neurological functions.
Normal Results :
The auditory brain stem values are in a normal range. This range varies among patients and instruments used.
What Abnormal Results Mean :
Abnormal findings may indicate a hearing loss, multiple sclerosis, or stroke.
Additional conditions under which the test may be performed:
Acoustic neuroma
Central pontine myelinolysis
Risks :
There are no risks.

Mammography
A mammogram is a special type of X-ray of the breasts. Mammograms can show tumors long before they are big enough for you or your health care provider to feel. Mammograms are recommended every year or two for women older than 40. They are also recommended for younger women who have symptoms of breast cancer or who have a high risk of the disease.
Mammograms are quick and easy. You stand in front of an X-ray machine. The person who takes the X-rays places your breast between two plastic plates. The plates press your breast and make it flat. This may be uncomfortable, but it helps get a clear picture. You will have an X-ray of each breast. A mammogram takes only a few seconds and it can help save your life.

MRI ( Magnetic Resonance Imaging )
What is an MRI scan?
An MRI (or magnetic resonance imaging) scan is a radiology technique that uses magnetism, radio waves, and a computer to produce images of body structures. The MRI scanner is a tube surrounded by a giant circular magnet. The patient is placed on a moveable bed that is inserted into the magnet. The magnet creates a strong magnetic field that aligns the protons of hydrogen atoms, which are then exposed to a beam of radio waves. This spins the various protons of the body, and they produce a faint signal that is detected by the receiver portion of the MRI scanner. The receiver information is processed by a computer, and an image is produced.
The image and resolution produced by MRI is quite detailed and can detect tiny changes of structures within the body. For some procedures, contrast agents, such as gadolinium, are used to increase the accuracy of the images.
When are MRI scans used?
An MRI scan can be used as an extremely accurate method of disease detection throughout the body. In the head, trauma to the brain can be seen as bleeding or swelling. Other abnormalities often found include brain aneurysms, stroke, tumors of the brain, as well as tumors or inflammation of the spine.
Neurosurgeons use an MRI scan not only in defining brain anatomy but in evaluating the integrity of the spinal cord after trauma. It is also used when considering problems associated with the vertebrae or intervertebral discs of the spine. An MRI scan can evaluate the structure of the heart and aorta, where it can detect aneurysms or tears.
It provides valuable information on glands and organs within the abdomen, and accurate information about the structure of the joints, soft tissues, and bones of the body. Often, surgery can be deferred or more accurately directed after knowing the results of an MRI scan.
What are the risks of an MRI scan?
An MRI scan is a painless radiology technique that has the advantage of avoiding x-ray radiation exposure. There are no known side effects of an MRI scan. The benefits of an MRI scan relate to its precise accuracy in detecting structural abnormalities of the body.
Patients who have any metallic materials within the body must notify their physician prior to the examination or inform the MRI staff. Metallic chips, materials, surgical clips, or foreign material (artificial joints, metallic bone plates, or prosthetic devices, etc.) can significantly distort the images obtained by the MRI scanner. Patients who have heart pacemakers, metal implants, or metal chips or clips in or around the eyeballs cannot be scanned with an MRI because of the risk that the magnet may move the metal in these areas. Similarly, patients with artificial heart valves, metallic ear implants, bullet fragments, and chemotherapy or insulin pumps should not have MRI scanning.
During the MRI scan, patient lies in a closed area inside the magnetic tube. Some patients can experience a claustrophobic sensation during the procedure. Therefore, patients with any history of claustrophobia should relate this to the practitioner who is requesting the test, as well as the radiology staff. A mild sedative can be given prior to the MRI scan to help alleviate this feeling. It is customary that the MRI staff will be nearby during MRI scan. Furthermore, there is usually a means of communication with the staff (such as a buzzer held by the patient) which can be used for contact if the patient cannot tolerate the scan.
How does a patient prepare for an MRI scan and how is it performed?
All metallic objects on the body are removed prior to obtaining an MRI scan. Occasionally, patients will be given a sedative medication to decrease anxiety and relax the patient during the MRI scan. MRI scanning requires that the patient lie still for best accuracy. Patients lie within a closed environment inside the magnetic machine. Relaxation is important during the procedure and patients are asked to breathe normally. Interaction with the MRI technologist is maintained throughout the test. There are loud, repetitive clicking noises which occur during the test as the scanning proceeds. Occasionally, patients require injections of liquid intravenously to enhance the images which are obtained. The MRI scanning time depends on the exact area of the body studied, but ranges from half an hour to an hour and a half.
How does a patient obtain the results of the MRI scan?
After the MRI scanning is completed, the computer generates visual images of the area of the body that was scanned. These images can be transferred to film (hard copy). A radiologist is a physician who is specially trained to interpret images of the body. The interpretation is transmitted in the form of a report to the practitioner who requested the MRI scan. The practitioner can then discuss the results with the patient and/or family.

EEG
An electroencephalogram (EEG) is a test to detect problems in the electrical activity of the brain.
How the Test is Performed
Brain cells communicate with each other by producing tiny electrical impulses. In an EEG, this faint electrical activity is measured by putting electrodes on the scalp.
The test is performed by an EEG technician in your health care provider's office, at a hospital, or at an independent laboratory. You will be asked to lie on your back on a bed or in a reclining chair.
The technician will apply between 16 and 25 flat metal discs (electrodes) in different positions on your scalp. The discs are held in place with a sticky paste. The electrodes are connected by wires to an amplifier and a recording machine.
The recording machine converts the electrical impulses into patterns that can be seen on a computer screen, as well as stored on a computer disk. Before computers, the activity was printed on paper. In either case, the electical activity looks like a series of wavy lines. You will need to lie still with your eyes closed because any movement can alter the results.
You may be asked to do certain things during the recording, such as breathe deeply and rapidly for several minutes or look at a bright flashing light.
How to Prepare for the Test
You will need to wash your hair the night before the test. Do not use any oils, sprays, or conditioner on your hair before this test.
Your health care provider may want you to stop taking certain medications before the test. Do not change or stop medications without first talking to your health care provider.
You should avoid all foods containing caffeine for 8 hours before the test.
Sometimes it is necessary to sleep during the test, so you may be asked to reduce your sleep time the night before. If you're asked to sleep as little as possible before the test, don't consume any caffeine, energy drinks, or other products that help you stay awake.
How the Test Will Feel
This test causes no discomfort. Although having electrodes pasted onto your skin may feel strange, they only record activity and do not produce any sensation. No significant electricity passes from the electrode into your skin.
Why the Test is Performed
EEG is used to help diagnose if you're having seizures and if so, what type. An EEG is also used to find the causes of confusion, and to evaluate head injuries, tumors, infections, degenerative diseases such as Alzheimer's disease, and abnormal changes in body chemistry that affect the brain.
It is also used to evaluate problems with sleep (see: sleep disorders) and to investigate periods of unconsciousness. The EEG may be done to show that the brain has no activity, in the case of someone in a deep coma. It can be helpful when trying to decide if someone's brain is dead.
EEG canNOT be used to measure intelligence.
Normal Results :
Brain electical activity has certain frequencies (the number of waves per second) that are normal for different levels of consciousness. For example, brain waves are faster when you are awake, and slower when you're sleeping. There are also normal patterns to these waves. These frequencies and patterns are what the EEG reader looks for.
What Abnormal Results Mean :
Abnormal results on an EEG test may mean:
- An abnormal structure in the brain (such as a brain tumor)
- Attention problems
- Cerebral infarction (tissue that is dead because of a blockage of the blood supply)
- Drug or alcohol abuse
- Encephalitis (inflammation of the brain)
- Head injury
- Hemorrhage (abnormal bleeding caused by a ruptured blood vessel)
- Migraines (in some cases)
- Seizure disorder (such as epilepsy or convulsions)
- Sleep disorder (such as narcolepsy)
Note: a normal EEG does not mean that a seizure did not occur.
Risks
The procedure is very safe. If you have a seizure disorder, a seizure may be triggered by flashing lights or by fast breathing ( hyperventilation) that is done during the test. The health care provider performing the EEG is trained to take care of you if this happens. It may be difficult to get the paste out of your hair, but it should come out after a few washings with regular shampoo.

Electroencephalogram (EEG)
An electroencephalogram (EEG) is a test that measures and records the electrical activity of your brain. Special sensors (electrodes) are attached to your head and hooked by wires to a computer. The computer records your brain's electrical activity on the screen or on paper as wavy lines. Certain conditions, such as seizures, can be seen by the changes in the normal pattern of the brain's electrical activity.
Why It Is Done
An electroencephalogram (EEG) may be done to:
Diagnose epilepsy and see what type of seizures are occurring. EEG is the most useful and important test in confirming a diagnosis of epilepsy.
Check for problems with loss of consciousness or dementia.
Help find out a person's chance of recovery after a change in consciousness.
Find out if a person who is in a coma is brain-dead.
Study sleep disorders, such as narcolepsy.
Watch brain activity while a person is receiving general anesthesia during brain surgery.
Help find out if a person has a physical problem (problems in the brain, spinal cord, or nervous system) or a mental health problem.
How To Prepare
Before the day of the electroencephalogram (EEG) test, tell your doctor if you are taking any medicines. Your doctor may ask you to stop taking certain medicines (such as sedatives and tranquilizers, muscle relaxants, sleeping aids, or medicines used to treat seizures) before the test. These medicines can affect your brain's usual electrical activity and cause abnormal test results.
Do not eat or drink foods that have caffeine (such as coffee, tea, cola, and chocolate) for 8 hours before the test.
Since the electrodes are attached to your scalp, it is important that your hair be clean and free of sprays, oils, creams, and lotions. Shampoo your hair and rinse with clear water the evening before or the morning of the test. Do not put any hair conditioner or oil on after shampooing.
To find certain types of abnormal electrical activity in the brain, you may have to be asleep during the recording. You may be asked not to sleep at all the night before the test or to sleep less (about 4 or 5 hours) by going to bed later and getting up earlier than usual. If your child is going to be tested, try to keep him or her from taking naps just before the test. If you know that you are going to have a sleep-deprived EEG, plan to have someone drive you to and from the test.
How It Is Done
An electroencephalogram (EEG) may be done in a hospital or in a doctor's office by an EEG technologist. The EEG record is read by a doctor who is specially trained to diagnose and treat disorders affecting the nervous system (neurologist).
How It Is Done continued...
You will be asked to lie on your back on a bed or table or relax in a chair with your eyes closed. The EEG technologist will attach 16 to 25 flat metal discs (electrodes) to different places on your head, using a sticky paste to hold the electrodes in place. A cap with fixed electrodes may be placed on your head instead of individual electrodes. In rare cases, these electrodes may be attached to the scalp with tiny needles.
The electrodes are hooked by wires to a computer that records the electrical activity inside the brain. A machine can show the activity as a series of wavy lines drawn by a row of pens on a moving piece of paper or as an image on the computer screen.
Lie still with your eyes closed during the recording, and do not talk to the technologist unless you need to. The technologist will watch you directly or through a window during the test. The recording may be stopped from time to time to allow you to stretch and reposition yourself.
The technologist may ask you to do different things during the test to record what activity your brain does at that time.
You may be asked to breathe deeply and rapidly (hyperventilate). Usually you will take 20 breaths a minute for 3 minutes.
You may be asked to look at a bright, flashing light called a strobe. This is called photic or stroboscopic stimulation.
You may be asked to go to sleep. If you cannot fall asleep, you may be given a sedative to help you fall asleep. If an EEG is being done to check a sleep problem, an all-night recording of your brain's electrical activity may be done.
An EEG takes 1 to 2 hours. After the test, you may do your normal activities. However, if you were sleep-deprived or given a sleep medicine, have someone drive you home after the test.
How It Feels
There is no pain with an electroencephalogram (EEG).
If paste is used to hold the electrodes, some paste may stay in your hair after the test, so you will have to wash your hair to remove it. If needle electrodes are used (which is rare), you will feel a brief, sharp prick (about like having a hair pulled out) when each electrode is inserted. If electrodes are placed in your nose, they may cause a tickling feeling and, rarely, some soreness or a small amount of bleeding for 1 to 2 days after the test.
If you are asked to breathe rapidly, you may feel lightheaded or have some numbness in your fingers. This reaction is normal. It will go away a few minutes after you start breathing normally again.
Risks
An electroencephalogram (EEG) is a very safe test. The electrical activity of your brain is recorded, but at no time is any electrical current put into your body. An EEG should not be confused with electroshock (electroconvulsive) therapy.
If you have a seizure disorder such as epilepsy, a seizure may be triggered by the flashing lights or by hyperventilation. If this occurs, the technologist is trained to take care of you during the seizure.
Results
An electroencephalogram (EEG) is a test that measures and records the electrical activity of your brain. Special sensors (electrodes) are attached to your head and hooked by wires to a computer. EEG test results are ready on the same or the next day.

ULTRASONOGRAFI ( USG )
What is ultrasonografi examination ?
Checking with Ultrasonografi or USG is one way of inspection organs to emit sound waves with high frequency that is directed into the body by means of ultrasonografi.
What that can be checked with the USG?
Each organ in the body can be checked with the USG provided that can reflect high-frequency sound waves, for example, heart, liver, gall bladder, pancreas, kidney, bladder and uterus. In practice, there are certain organs that are less good to reflect high-frequency sound waves, namely that contains the lungs, such as air cavity, stomach and intestine. These organs can not be checked with the USG.
What's difference can be detected with the USG?
Swelling or shrinkage / contraction organs in detail. Tumors on the organ with a minimum of 5 mm in diameter, and often we can distinguish between malignant tumors and benign tumors. Stone in the gall bladder / kidney with a diameter of at least 2 mm. Sumbatan channel in the bile or urine channel. The existence of abses (pus) on the organ in the body. The existence of a liquid or bleeding in the body cavity. To make detection / aberration in the blood vessels in the body. Determine the function of the heart kwalitatif, and kwantitatif, to determine the leakage / constriction valve, etc..
Setting the age pregnancy, placenta location, gender of the fetus in pregnancy, etc..
In the content, such as ovary cyst, tumors, etc..
WHAT benefit examination with USG compared with Checking other ?
Checking with the USG can detect the difference in the anatomical organs quickly and accurately. This allows doctors to plan for inspection of a more advanced, so the diagnosis can certainly were more early. This benefit patients, because the treatment can be started earlier and healing can be accelerated. In addition to the USG examination does not cause pain for patients and does not require special preparation such as fasting or diet-specific.
.
PERSIAPAN the inspection:
Does not require special preparation, except in the inspection gall bladder filled in the circumstances that require fasting for at least 8 hours, Before the inspection, you may be asked to drink 1 liter of water. With drinking water, will make it easier to become a doctor to see the womb. Bladder is located in front of the uterus. If the bladder is full, then pushed to the front of the uterus and exit from the pelvic area and can be easily seen through the USG. If the bladder is empty, the uterus is located further down in the pelvis and will make it difficult to see.
WHAT side effect the inspection?
USG examination does not cause harmful side effects for the patient and the fetus. USG also checks carried out safely many times even within a very short time (every day, for example).
BENEFIT TO MONITOR CONDITIONS USG PREGANCCY :
• To identify the early pregnancy.
• To show the size and speed of growth of embryo or fetus.
• To measure the fetal head, abdomen, thigh or to determine the duration or length of pregnancy.
• To identify fetal Down syndrome with particular.
• To identify fetal abnormalities, such as hidrosefalus.
• To identify the location, size, maturity and Hampi Hampi or abnormalities.

CERVICAL CERVIC CANCER
Cervical cancer (serviks) or karsinoma serviks uterus cancer is the number two killer of women in the world after breast cancer. In Indonesia, cervix cancer even occupy the first rank. Cancer serviks the entrance to the stadium is more often cause death in a relatively quick period of time.
Serviks or cervix / uterus mouth is the end of the uterus to the prominent hole sexual intercourse (vagina). Serviks cancer developing in stages, but progressive. The occurrence of cancer this process begins with cells that mutation and develop into cells that occur displastik aberration epitel called displasia. Displasia light from the start, are displasia, displasia weight, and eventually become karsinoma in-situ (KIS), and then develop into more karsinoma Invansive. Level displasia and KIS also known as the level of pre-cancer. From displasia become karsinoma in-situ take 1-7 years, while the in-situ karsinoma become karsinoma Invansive ranging 3-20 years.
RISK FACTORS INTO
There are several factors that can increase the risk of cancer serviks, among other
is:
This factor is the main risk factors, women who have sex at the age of less than 17 years have a risk 3 times larger than the married at the age of 20 years.
The sexual behavior of a mutually sex partners will increase the transmission of sexual diseases. The disease is transmitted infections such as human papilloma virus (HPV) has been proven to increase the incidence of cancer serviks, penis and vulva. Serviks exposed to the risk of cancer to be 10 times higher in women who have sexual partners, 6 or more. In addition, the herpes simplex virus type-2 can be a factor companion.
Women chain has more than 2 times the risk of cancer affected serviks compared with women who do not smoke.
There are several studies that conclude that defisiensi acid folat can increase displasia risk of occurrence of mild and moderate, and may also increase the risk of occurrence of cancer in women who serviks food low beta-carotene and retinol (vitamin A)
Recognizing APPROACH-APPROACH
In phase prakanker, there is often no symptoms or signs typical. However, sometimes can be found symptoms as follows:
Leucorrhoea or exit from the vagina thin liquids.
Bleeding after sexual intercourse, which then continues to be a morbid bleeding.
The emergence of bleeding after a period off
In the phase out of liquids can Invansive yellowish color, smell and can be mixed with blood.
Symptoms arise anemia occurs when chronic bleeding.
Arising pelvic pain (pelvis) or in the lower abdomen when a pelvic inflammation.
At the stadium information, the body becomes emaciated because of malnutrition, ederma feet, arising bladder irritation and bearing the bottom of the large intestine (rectum), the formation fistel vesikovaginal or the rektovaginal, or symptoms arising as a result of far Metastasis
PREVENT better than treat
Death on serviks cancer cases occur because most people who have been treated in the stadium more. Even with this finding cancer early in the stadium, the possibility of this disease can be cured up to almost 100%. Actual fact this very serviks cancer can be prevented. According to the OBGYN specialist from New York University Medical Center, dr. Steven R. Goldstein, the key is early detection.
Around 90-99 percent serviks type of cancer caused by human papillomavirus (HPV). The virus can be transferred through sexual intercourse and can be present in different variations. There are several cases of HPV virus that down by itself, and that there continues to be cancer serviks, enough so that threaten the health of female anatomy this one.
Now, the 'weapon' best to prevent this is a form of cancer screening, called a PAP smear, and screening is very effective. Pap smear is an examination sitologi introduced by Dr. GN Papanicolaou in the year 1943 to know that there is violence (cancer) with a microscope. This inspection is done easily, quickly and not sick. The problem is, many women who do not want to undergo this examination, and the cancer is usually serviks had arisen in women who had never examined themselves or do not want to do the inspection.
Pap smear examination is recommended to be done by the women regularly once
year in succession in three years time when sexual intercourse has been active and aged at least 21 years old. When the results of three years in succession normal, further investigation can be conducted every three years
Tips for Preventing Cervical Cancer
1. Women must be sexual hygiene, the cleanliness of womanhood.
2. When signs occur in the cervix rocker immediately do pap smear test.
3. Go for a good sexual relationship.
4. For men who do not circumsisi (circumcision), must maintain because of sexual higienitas
vulnerable as the HPV virus carrier.
5. Do not keep changing partners in sexual relations (sex-partner), because
The main entrance is the cause of the HPV virus.

According to the OBGYN specialist from New York University Medical Center, dr. Steven R. Goldstein, the key is early detection.
Around 90-99 percent serviks type of cancer caused by human papillomavirus (HPV). The virus can be transferred through sexual intercourse and can be present in different variations. There are several cases of HPV virus that down by itself, and that there continues to be cancer serviks, enough so that threaten the health of female anatomy this one.
Now, the 'weapon' best to prevent this is a form of cancer screening, called a PAP smear, and screening is very effective. Pap smear is an examination sitologi introduced by Dr. GN Papanicolaou in the year 1943 to know that there is violence (cancer) with a microscope. This inspection is done easily, quickly and not sick. The problem is, many women who do not want to undergo this examination, and the cancer is usually serviks had arisen in women who had never examined themselves or do not want to do the inspection.
Pap smear examination is recommended to be done by the women regularly once
year in succession in three years time when sexual intercourse has been active and aged at least 21 years old. When the results of three years in succession normal, further investigation can be conducted every three years
Tips for Preventing Cervical Cancer
1. Women must be sexual hygiene, the cleanliness of womanhood.
2. When signs occur in the cervix rocker immediately do pap smear test.
3. Go for a good sexual relationship.
4. For men who do not circumsisi (circumcision), must maintain because of sexual higienitas
vulnerable as the HPV virus carrier.
5. Do not keep changing partners in sexual relations (sex-partner), because
The main entrance is the cause of the HPV virus.

Spirometry
Spirometry (meaning the measuring of breath) is the most common of the Pulmonary Function Tests (PFTs), measuring lung function, specifically the measurement of the amount (volume) and/or speed (flow) of air that can be inhaled and exhaled. Spirometry is an important tool used for generating pneumotachographs which are helpful in assessing conditions such as asthma, pulmonary fibrosis, cystic fibrosis, and COPD.
Procedure
The basic FVC test varies slightly depending on the equipment used.
Generally, the patient is asked to take the deepest breath they can, and then exhale into the sensor as hard as possible, for as long as possible. It is sometimes directly followed by a rapid inhalation (inspiration), in particular when assessing possible upper airway obstruction. Sometimes, the test will be preceded by a period of quiet breathing in and out from the sensor (tidal volume), or the rapid breath in (forced inspiratory part) will come before the forced exhalation.
During the test, soft nose clips may be used to prevent air escaping through the nose. Filter mouthpieces may be used to prevent the spread of microorganisms, particularly for inspiratory maneuvers.
Limitations of test
The maneuver is highly dependent on patient cooperation and effort, and is normally repeated at least three times to ensure reproducibility. Since results are dependent on patient cooperation, FEV1* and FVC can only be underestimated, never overestimated.(*FEV1 can be overestimated in people with some diseases - a softer blow can reduce the spasm or collapse of lung tissue to elevate the measure)
Due to the patient cooperation required, spirometry can only be used on children old enough to comprehend and follow the instructions given (typically about 4-5 years old), and only on patients who are able to understand and follow instructions - thus, this test is not suitable for patients who are unconscious, heavily sedated, or have limitations that would interfere with vigorous respiratory efforts. Other types of lung function tests are available for infants and unconscious persons

What is the BAER test?
The hearing test known as the brainstem auditory evoked response (BAER) or brainstem auditory evoked potential (BAEP) detects electrical activity in the cochlea and auditory pathways in the brain in much the same way that an antenna detects radio or TV signals or an EKG detects electrical activity of the heart. The response waveform consists of a series of peaks numbered with Roman numerals: peak I is produced by the cochlea and later peaks are produced within the brain. The response from an ear that is deaf is an essentially flat line. In the sample recordings shown below, Puppy 1 heard in both ears, Puppy 2 was deaf in the left ear, Puppy 3 was deaf in the right ear, and Puppy 4 was deaf in both ears. Because the response amplitude is so small it is necessary to average the responses to multiple stimuli (clicks) to unmask them from the other unrelated electrical activity that is also present on the scalp (EEG, muscle activity, etc).
The response is collected with a special computer through extremely small electrodes placed under the skin of the scalp: one in front of each ear, one at the top of the head, and one between and behind the eyes. It is rare for a dog to show any evidence of pain from the placement of the electrodes - if anything the dog objects to the gentle restraint and the irritation of wires hanging in front of its face. The stimulus click produced by the computer is directed into the ear with a foam insert earphone. Each ear is tested individually, and the test usually is complete in 10-15 minutes. Sedation or anesthesia are usually not necessary unless the dog becomes extremely agitated, which can usually be avoided with patient and gentle handling. A printout of the test results, showing the actual recorded waveform, is provided at the end of the procedure. Test results are confidential, but anonymous details will be used in Dr. Strain's ongoing deafness research for later publication and education of veterinary practitioners.

Pregnancy & Prenatal Testing:
Infection with the hepatitis B virus causes an inflammation of the liver. People with acute hepatitis B may have symptoms such as fatigue, nausea, and jaundice. Most people will get better without any intervention, but about 1% to 3% become carriers. Some of those chronically infected will have progressive liver damage that can lead to liver cancer and death.
The hepatitis B screening test is called hepatitis B surface antigen. It detects a protein produced by the virus and can detect a hepatitis B infection even before it is causing symptoms. If a woman who is considering getting pregnant tests positive for hepatitis B, she should talk to her health care provider about how long she should wait to allow the infection to resolve before becoming pregnant.
It is important to detect active hepatitis B infections in pregnant women because newborns are especially vulnerable to developing chronic infection; up to 90% of those who become infected with hepatitis B in utero will become carriers. If a hepatitis infection is detected in a pregnant woman, she can be monitored and the baby can receive treatment at birth to minimize the risk of it developing hepatitis B.
A negative test for the virus means either that there is no current infection or there is not yet a sufficient amount of the antigen to be detected. If a woman participates in high-risk activities that may transmit the hepatitis B virus (such as unprotected sexual contact or intravenous drug use), retesting later in the pregnancy is generally advised.
