About Hepatitis B Surface Antigen Lab Test in Gresham
Understanding what the Hepatitis B Surface Antigen test measures helps clarify its role in diagnosing and monitoring hepatitis B infection.
Hepatitis B Surface Antigen, often abbreviated as HBsAg, is a protein found on the outer envelope of the hepatitis B virus. Its presence in the blood generally indicates that the virus is present and that the person can transmit the infection to others.
This test is frequently used as a first-line screen because HBsAg becomes detectable before other markers and remains positive in chronic carriers. A positive result does not by itself distinguish between acute and chronic infection; that distinction depends on how long the antigen persists and on additional test results.
Because the antigen can appear within weeks of exposure, the test is valuable for early detection. It is also used to monitor treatment response and to screen individuals who may have been exposed through blood, sexual contact, or other routes.
