Rapid and quantitative detection of hepatitis B virus

HBsAg is the surface antigen of the hepatitis B virus (HBV). It indicates current hepatitis B infection. Biotime HBsAg Rapid Quantitative Test kit can detect the specimen of serum and plasma.

Quantitative HBV surface antigen (HBsAg) testing is intended for use in individuals with a confirmed diagnosis of Hepatitis B Virus infection based on positive HBsAg, Anti-HBs antibody and/or Anti-core antigen (anti-HBc) antibody test results. Quantitative HBsAg testing has utility in assessing HBV replication in the absence and presence of antiviral therapy, which may inform monitoring treatment response and relapse in the setting of initial and prolonged antiviral therapy, respectively. Recent studies indicate that rapid decay and loss of HBsAg expression are strong predictors of sustained HBV clearance.
