The hepatitis B antibody immunity panel determines if you have been properly immunized against the hepatitis B virus (HBV), either through acute infection or immunization.
What is hepatitis B?
Hepatitis B is a liver infection caused by the hepatitis B virus. Hepatitis B is transmitted when blood, semen, or another body fluid from a person infected with the hepatitis B virus enters the body of someone who is not infected. This can happen through sexual contact; sharing needles, syringes, or other drug-injection equipment; or from mother to baby at birth. For some people, hepatitis B is an acute, or short-term, illness but for others, it can become a long-term, chronic infection.
What is the difference between an acute and chronic illness?
Acute hepatitis B refers to a short-term infection that occurs within the first 6 months after someone is infected with the virus. The infection can range in severity from a mild illness with few or no symptoms to a serious condition requiring hospitalization. Some people, especially adults, are able to clear, or get rid of, the virus without treatment. People who clear the virus become immune and cannot get infected with the hepatitis B virus again.
Chronic hepatitis B refers to a lifelong infection with the hepatitis B virus. The likelihood that a person develops a chronic infection depends on the age at which someone becomes infected. Up to 90% of infants infected with the hepatitis B virus will develop a chronic infection. In contrast, about 5% of adults will develop chronic HBV. Over time, chronic hepatitis B can cause serious health problems, including liver damage, cirrhosis, liver cancer, and even death.
Who should be tested for HBV?
Although anyone can get hepatitis B, the Centers for Disease Control and Prevention (CDC) recommends testing for HBV for anyone in the following categories:
- All pregnant women
- Household and sexual contact of people with HBV
- People born in certain parts of the work that have increased risk of HBV
- People with HIV, receive chemotherapy, or are on hemodialysis
- People who inject drugs
- Men who have sex with men
What are the symptoms of HBV?
Many people with hepatitis B do not have symptoms and do not know they are infected. If symptoms occur, they can include:
- Loss of appetite
- Dark urine
- Upset stomach
- Nausea and vomiting
- Grey-colored stool
- Joint pain
Can HBV be prevented?
Yes. The best way to prevent hepatitis B is by getting vaccinated. The hepatitis B vaccine is typically given as a series of 3 shots over a period of 6 months. The entire series is needed for long-term protection.
Who should get vaccinated against HBV?
The CDC recommends that all infants be vaccinated. The vaccine is also recommended for people living with someone infected with hepatitis B, travelers to certain countries, and healthcare and public safety workers exposed to blood. People with high-risk sexual behaviors, men who have sex with men, people who inject drugs, and people who have certain medical conditions, including diabetes, should talk to a healthcare provider about getting vaccinated.
What type of HBV test is being performed?
The blood test being performed is a Hepatitis B Antibody Immunity Panel. This test is used to detect antibodies in the blood that were produced in response to an HBV surface antigen, either through infection or immunization.
What’s the difference between the antibody test and the surface antigen test?
The antibody test detects substances that were produced in response to the HBV virus, either through acute infection or immunization.
The antigen test looks for HBsAg, a protein on the surface of the hepatitis B virus, so the antigen test can detect an active infection. The antigen test can also be used to identify chronic infections.
What should I do if my results are positive or negative?
It is always recommended you meet with a healthcare provider to determine what your laboratory test results mean to you. Your healthcare provider will review all of your test results and, combined with your health history, will be able to provide an accurate picture of your health status.
If your results were positive: If your test is positive for HBV antibodies, you have been properly immunized against HBV or the virus has cleared and you are immune due to a natural acute infection.
If your results were negative: A negative test means there is no HBV antibodies found in the blood so you have not been exposed to HBV, either through infection or immunization. You should talk to your healthcare provider to see if you should be vaccinated.
How do I get tested?
To order your own lab tests, you just need to follow these three easy steps:
- Complete a lab order form for your test online and print it out to take with you to the DLO Patient Service Center. Follow the instructions on the laboratory test order form if fasting is required for the testing you are ordering.
- Visit any DLO Patient Service Center throughout Oklahoma. Check in with our friendly staff and give them your completed order form. Full payment is due at time of service before sample collection is performed. Note that we accept all major credit cards and checks. Unfortunately, we cannot accept cash payments. Have one of our skilled phlebotomists draw a blood sample or take a urine sample, who will send your sample to our laboratory for testing.
- Create a MyQuest™ account and view your test results through the MyQuest online patient portal. Test results are available through MyQuest within 7-10 business days of completing your lab work.
