Order Hepatitis B Surface Antigen Lab TestThe Hepatitis B Surface Antigen Lab Test is a blood test that detects a protein found on the outer shell of the hepatitis B virus.

About Hepatitis B Surface Antigen Lab Test in Pico Rivera
Understanding what the hepatitis B surface antigen represents helps clarify why it is such a foundational test for liver health.
Hepatitis B surface antigen, often abbreviated HBsAg, is a protein that sits on the surface of the hepatitis B virus. When the virus is present in the body, this antigen can be detected in the bloodstream. It typically appears early in the course of infection, before symptoms develop and before the body mounts a measurable immune response.
Because HBsAg is the earliest detectable marker, it serves as a primary screening tool for acute hepatitis B. Its continued presence beyond six months generally indicates a chronic infection, in which the virus persists and may gradually affect liver function over time. A negative result usually means no current infection is detected, though it does not by itself confirm immunity.
This test is often ordered alongside other hepatitis markers, such as antibodies or viral DNA, to build a fuller picture of infection status, immune response, and potential for transmission. Results are interpreted by a healthcare provider in the context of a person's history, symptoms, and other laboratory findings.
