The test reports both the HBsAg - Quantitative result and the HBsAg Value, which together indicate the concentration of hepatitis B surface antigen in the blood. However, the quantitative HBsAg is not a direct measure of viral load. The test result is often interpreted along with other crucial investigations such as HBV DNA (viral load), liver function tests, and other hepatitis B serology markers for diagnosis and monitoring. The Hepatitis B s (Surface) Antigen Quantitative test is essential for monitoring the effectiveness of treatments such as antiviral therapy, and for implementing measures to prevent the spread of Hepatitis B virus to others.
