Abstract
The aim of this study was to clarify the percentage of samples considered false positive for hepatitis B surface antigen (HBsAg) in relation to the HBsAg concentration. The HBsAg concentrations were measured in 41,186 samples using chemiluminescent enzyme immunoassay. Samples with a concentration of ≥0.05 IU/mL were considered positive. The criteria for classifying a result as false positive were as follows: negative for anti-HBc, HBeAg, anti-HBe, and HBV-DNA as well as negative for HBsAg examined with the sample obtained on other day.
