Order Hepatitis B Surface Antigen Lab TestThe Hepatitis B Surface Antigen Lab Panel is a blood test designed to detect a specific protein that appears on the outer envelope of the hepatitis B virus.

About Hepatitis B Surface Antigen Lab Test in Boynton Beach
Hepatitis B surface antigen (HBsAg) is the earliest serological marker of hepatitis B virus infection, and its detection is central to diagnosing both acute and chronic cases.
When a person is exposed to the hepatitis B virus, the surface antigen typically becomes detectable in the blood before symptoms appear or liver enzyme levels rise. In an acute infection, HBsAg usually remains present for a matter of weeks to several months as the immune system works to clear the virus. If the antigen persists beyond six months, the infection is classified as chronic, a state that can carry long-term consequences for liver health.
The test works by using laboratory reagents that bind specifically to the hepatitis B surface antigen. If the antigen is present in the blood sample, the reaction produces a detectable signal, which the lab reports as reactive or positive. A non-reactive or negative result means the antigen was not found at the time of testing, though timing matters: very early infection or a resolved past infection can both yield a negative result.
Because the surface antigen is the first marker to emerge and the last to disappear in many cases, it serves as a reliable indicator of current infectivity. A positive result does not distinguish by itself between acute and chronic infection; that determination depends on how long the antigen has been present and on additional tests such as the hepatitis B surface antibody and core antibody. Clinicians interpret the surface antigen result alongside a patient's history and other laboratory findings to build an accurate picture.
