HBSAG Full Form in Medical term is Hepatitis B Surface Antigen. Hepatitis B infection is indicated by a “positive” and “reactive” in HBsAg test result. The presence of the virus that causes hepatitis B in your blood (known as the “surface antigen”) can be determined by doing this test.
Should a person test “positive,” more testing is required to distinguish between a “acute” infection and a “chronic” one. Hepatitis B virus infection and subsequent transmission to others is indicated by an affirmative HBsAg test result.
Acute and chronic infection with the hepatitis B virus can be diagnosed with the help of the HBsAg test. It guides subsequent plans for therapy for the disease and helps determine the necessity of post-test counseling & linkage to care. You can also use it to find out if your HBV immunity was the result of a previous infection or a vaccination.
The levels of HBsAg are outside of any established normative range. Rather, the outcomes of the tests are classified as either good, negative, or inconclusive. Under 5 mIU/mL is regarded to be negative, whereas over 12 mIU/mL indicates protective immunity. When the result is between five and twelve mIU/mL, it is inconclusive and needs to be retested.
