How accurate is HBsAg test?
Serodia HBsAg was evaluated in three studies on 1040 patient samples [33, 38, 42], all published before 2000, with pooled sensitivity and specificity of 95.8% (95% CI: 93.4, 97.5) and 99.8% (95% CI: 99.1, 100), respectively.
Can HBsAg be false positive?
There are reports of false positivity of HBsAg among healthy blood donors, however, scanty data could be found for adults undergoing health screening programs. This article aims to report the false positive results of HBsAg due to the recent Hepatitis B vaccine among healthy male adults.
Is HBsAg test accurate?
In those who were younger than 2 years, the diagnostic accuracy of the HBsAg test card was 100%. Then, 1272 samples were tested for anti-HBs rapid test card. The sensitivity was 91.8% and the specificity was 96.5%.
What happens if HBsAg is positive?
If the “HBsAg” was positive, this means that you are either chronically infected with hepatitis B or were recently infected. If only the “anti-HBc” was positive, it is most likely that you either had a “false-positive” test or are immune to hepatitis B infection (had hepatitis B infec- tion sometime in the past).

A public health investigation subsequently determined that the false-negative results were caused by a surface antigen mutation. Notably, several commercial HBsAg testing kits cannot detect this mutant virus, making it a challenging pathogen for public health surveillance and intervention efforts (1).
