Order Hepatitis B Surface Antigen Lab TestThe Hepatitis B Surface Antigen Lab Test is a blood test that detects a specific protein on the surface of the hepatitis B virus. Its presence is the earliest serological marker of acute hepatitis B infection and can also indicate chronic infection.
About Hepatitis B Surface Antigen Lab Test in Peekskill
Hepatitis B Surface Antigen (HBsAg) is a protein found on the outer envelope of the hepatitis B virus.
When the virus is present in the bloodstream, HBsAg can be detected before other markers such as antibodies appear. This makes it a primary tool for identifying acute infection early in its course.
In some individuals, HBsAg remains detectable for longer than six months, which defines chronic hepatitis B infection. Persistent antigenemia signals that the virus continues to replicate and that the person may be capable of transmitting the infection to others.
The test is used in several contexts: evaluating someone with symptoms or abnormal liver enzymes, screening individuals with risk factors, and monitoring people known to have hepatitis B. A negative result generally means the antigen is not present, though timing and other clinical findings are always considered.
