Hepatitis B Surface Antigen  - Quantitative

Hepatitis B Surface Antigen - Quantitative

Hepatitis B is a liver infection caused by the hepatitis B virus (HBV). It can range in severity from a mild illness lasting a few weeks to a serious, lifelong condition that can lead to liver disease or liver cancer. The Hepatitis B Surface Antigen (HBsAg) is a protein on the surface of the hepatitis B virus. It is one of the earliest markers of hepatitis B infection. A quantitative HBsAg test measures the amount of HBsAg in a blood sample, and is used to monitor the levels of the virus in individuals with chronic hepatitis B infections.

  • Test Name Hepatitis B Surface Antigen (HBsAg) - Quantitative
  • Sample Type Blood
  • Preparations Required No fasting or special preparation is needed for this test. Make sure to inform your doctor if you are on any medication.

Quantitative HBsAg testing is an important tool in managing hepatitis B. By quantifying the levels of HBsAg, healthcare professionals can assess the stage of the infection, monitor the efficacy of antiviral therapy, and make informed decisions regarding the course of treatment. This test is particularly useful for individuals undergoing antiviral therapy for chronic hepatitis B, as a decrease in HBsAg levels can be an indication of response to therapy.
