The Hepatitis B Surface Antigen Test checks a small blood sample for a part of the hepatitis B virus. Many people call it the HBsAg test or the Hep B surface antigen test. If your doctor asked for screening, you can book at participating labs on LabFinder and choose a time that works for you.
This test is also called a Hepatitis B antigen test or HBsAg screening. It looks for the surface antigen of the virus in your blood. A positive result suggests a current infection and means you should talk with your doctor about the next steps. A negative result means the antigen was not found at the time of testing.
Common reasons: routine screening, tests during pregnancy, follow up after a possible exposure, checking unexplained liver enzyme changes, and screening before certain medical treatments. Your doctor can guide you on timing and any follow up tests.
Check in with your ID and lab order. A technician cleans your arm and draws a small tube of blood. A bandage is placed and you can head out. Plan about 15 to 30 minutes for the whole visit.
Yes, this is a quick, routine blood draw and is considered very safe. You might feel a quick pinch, notice a small bruise, or feel a little lightheaded for a moment afterward, but those effects usually fade quickly. Be sure to tell the staff if you take blood thinners, have a bleeding disorder, or if you have fainted during blood draws before. They will take extra care to keep you comfortable.
Food and drink: no fasting is usually needed unless other labs require it. Hydrate: drink water so veins are easier to find. Medications: take your regular medicines unless your doctor says otherwise and bring a list. Tell the staff: mention any recent blood transfusion or antibody treatment. Always follow any instructions from your doctor or the lab and bring prior results if you have them.
Acute hepatitis B, chronic hepatitis B, liver inflammation, risk of passing the virus to others, and the need for treatment or closer monitoring. Results are read in context. Your doctor will review your history and symptoms before recommending next steps.
