The HBsAg Rapid Test is a direct binding test for the visual detection of hepatitis B surface antigen (HBsAg) in serum or plasma as an aid in the diagnosis of hepatitis B infection. OneStep HBsAg Rapid 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.
