One Step HBsAg Test is a rapid direct binding test for the visual detection of hepatitis B surface antigen (HBsAg) in serum/plasma/whole blood as an aid in the diagnosis of hepatitis B infection. One Step HBsAg Test is based on the principle of sandwich immunoassay for determination of HBsAg in serum/plasma/whole blood. Monoclonal and polyclonal antibodies are employed to identify HBsAg specifically. This one step test is very sensitive and only takes about 25 minutes. Test results are read visually without any instrument. One Step HBV (5 in 1) Test is a rapid direct test for the visual detection of HBsAg, Anti-HBs, HBeAg, Anti-HBe, Anti-HBc. It is based on the principle of immunology and combined with colloidal gold technology. One Step ANTI-HCV Test is a rapid direct binding test for the visual detection of hepatitis C antibodies (anti-HCV) in serum/plasma/whole blood as an aid in the diagnosis of hepatitis C infection.One Step ANTI-HCV Test is based on the principle of double antigen sandwich immunoassay for determination of anti-HCV in serum/plasma/whole blood.Purified recombinant antigens are employed to identify anti-HCV specifically.This one step test is very sensitive and only takes about 10-20 minutes.Test results are read visually without any instrument. One Step Malaria P.f Test is a immunochromatographic (rapid) test for the qualitative detection of antigens of Plasmodium falciparum simultaneously in human serum/plasma.
