Why HBsAg Test is required? Concise information
HBsAg (Hepatitis B Surface Antigen) is a blood test that detects the presence of the hepatitis B virus (HBV) in the body. It's a key test for diagnosing hepatitis B infection.
Here's how it works:
- HBsAg is a protein found on the surface of the hepatitis B virus.
- When the virus infects the liver, it releases this protein into the bloodstream.
- The HBsAg test detects the presence of this protein in the blood, indicating that the person is infected with HBV.
- A positive result means the person is currently infected or has been infected in the past.
- A negative result means the person is not infected or has cleared the infection.
The HBsAg test is important for:
- Diagnosing acute or chronic hepatitis B infection
- Screening blood donors and organ donors
- Monitoring the effectiveness of hepatitis B treatment
- Identifying individuals who need vaccination or further testing
Keep in mind that a positive result requires further testing to determine the stage and severity of the infection.
