What do I need to know about hepatitis B testing?
We offer the Hepatitis B Surface Antigen (HBsAg) blood test that looks for antigens that the hepatitis B virus produces. This test looks for early signs of a new or existing hepatitis B infection...in fact, the test is so sensitive that it can detect signs of infection before symptoms appear.
Will I need to have a physical exam for this test?
No. When you go to the LabCorp or Quest Diagnostics test center near you, you'll just need to provide a quick blood sample. No undressing or exams necessary.
How quickly can I get my results?
Hepatitis B tests can have a very fast turnaround. If you're getting tested for more than one STD, we will release all results at the same time...typically in 2 to 3 business days.
What do I need to know about the test results?
Hepatitis B tests are either positive or negative. Positive means that there is evidence of the virus and negative means that, at the time the test was taken, there was no presence of infection.
Note: As with HIV and hepatitis C, if you test positive for hepatitis B, you should not donate blood.
I may have had the hepatitis B vaccine when I was a kid, but I'm not sure. Would it have "worn off"?
Unlike other hepatitis virus strains, there is a safe and effective vaccine for hepatitis B. If you've been vaccinated, you're protected from contracting this virus...there is no need for a booster.
Hepatitis B is a three shot vaccine series, given over the course of 6 months. Unfortunately, many people have hepatitis B without realizing it...so if you're considering the vaccine, you may want to get tested to know your hepatitis B status, first.
Also, if you're a young adult, you may have been vaccinated as a baby or child...although there is no harm in re-vaccination, it's worth checking your pediatrician's records to see if you completed the vaccine in the past.
