One Step HBsAg Test is a rapid direct binding test for the qualitative detection of hepatitis B surface antigen (HBsAg) in human serum/plasma as an aid in the clinical assessment of hepatitis B infection.
The test is based on the principle of sandwich immunoassay for determination of HBsAg in serum/plasma. Monoclonal and polyclonal antibodies are employed to identify HBsAg specifically. This one step test is very sensitive and only takes about 10-20 minutes. Test results are read visually without any instrument.
