The Hepatitis B Surface Antigen (HBsAg) lab test checks your blood for a protein that appears on the surface of the hepatitis B virus. It is ordered to find out if you are currently infected with hepatitis B, which can be transmitted through blood, sex, or from mother to baby during birth.

What it measures

  • Hepatitis B surface antigen (HBsAg) — The main marker: if present, it means the virus is in your blood and you can pass it to others.
  • Hepatitis B surface antibody (anti-HBs) — Often tested alongside HBsAg; a positive result usually means you are protected from hepatitis B, either from vaccination or past infection.
  • Hepatitis B core antibody (anti-HBc) — Another marker that can show if you have ever been exposed to the virus, even if it is no longer active.

Who it is for

A doctor or clinic may order this test if you have symptoms like yellow skin or eyes, if you are pregnant, or if you have risk factors such as contact with an infected person or a history of sharing needles.

Preparation

No fasting or special preparation is needed for this blood test. You can eat and drink normally before your appointment.

Results and what they mean

Results are reported as positive (antigen found) or negative (not found), sometimes with a numerical value. A positive result usually means you have a current hepatitis B infection and may need further tests.

What does a positive result mean for my partner?

A positive result means you can pass the virus to others. Your partner may need testing and vaccination, so talk with your doctor.
