Hepatitis B Surface Antigen (HBsAg)

What Is the Hepatitis B Surface Antigen (HBsAg) Test?

The Hepatitis B Surface Antigen (HBsAg) test detects an active infection by the hepatitis B virus (HBV). It identifies the virus during the initial infection phase as well as in the chronic carrier state.

Where Used

Timing of Sample Collection: The test is valid for samples taken at least 2-3 weeks after potential exposure or infection. During this time, the virus copies have reached detectable levels > (99% reliability)

The test is used mainly for preventive and diagnostic purposes.

The test is used primarily for preventive and diagnostic purposes.

  1. Fast detection of HBV infection and immediate effective treatment.
  2. Between sexual partners to avoid transmission from a non-infected carrier
  3. Educating younger individuals to be vigilant against seemingly healthy carriers
  4. Prenatal and pre-surgical screening for timely implementation of appropriate measures

Diagnostic Use:

  1. Positive Result, confirmation with HBeAg, Anti-HBc IgG-IgM tests, or molecular biology tests like HBV PCR to avoid false positives.
  2. Negative result near window period, Sample may need to be retested after some time to confirm the result.
  3. Negative result with strong HBV indications, confirmation with molecular biology tests like HBV PCR is needed.
Reference Values ​​-Normal Laboratory :

In non-immunocompromised adults, a negative result is typically valid against both positive and negative control sera.

Hepatitis B is a liver infection caused by the hepatitis B virus (HBV). The virus can cause a wide range of symptoms, from asymptomatic to severe liver disease, including cirrhosis and liver cancer. The Hepatitis B Surface Antigen (HBsAg) test is an important part of checkups for evaluating potential exposure to the virus and the likelihood of infection.

HBV is a DNA virus belonging to the Hepadnaviridae family. It is primarily transmitted through blood and bodily fluids, notably through sexual contact, contaminated needles, or other blood transmission methods, and from mother to child during birth. The virus can also be transmitted through contaminated medical tools or procedures. Hepatitis B can lead to immediate or long-term complications, such as advanced liver disease and liver cancer.

The HBsAg test is an immunochemical assay that detects the presence of this antigen in the body, indicating infection by the hepatitis B virus and potential exposure. This test can be performed on any blood or bodily fluid, such as serum or plasma, and is typically conducted in medical diagnostic laboratories.

The HBsAg test is a simple, quick, and reliable procedure usually performed as part of a broader checkup program or in environments where there is suspected exposure to HBV. Detection of HBsAg can also be performed in professional settings, such as among healthcare workers or individuals at high risk of infection.

In cases where the HBsAg test is positive, further tests and evaluation by a physician are essential. This may include other tests for HBV, such as HBeAg, Anti-HBc antibodies, and HBV DNA viral load, These test help determine the disease status, viral activity, and the need for treatment.

Overall, the HBsAg test is a crucial tool in the evaluation process for hepatitis B. Early detection and appropriate treatment are vital for preventing complications and improving patient outcomes.
