One step Anti-HIV1+2 Test is a rapid direct binding screening test for the presence of antibodies to HIV1 and HIV2 viruses. The test is based on the principle of double antigen sandwich immunoassay for detection of Anti-HIV in serum/plasma. Purified recombinant antigens are employed to identify Anti-HIV specifically. HIV 1+2 Whole Blood Cassette test is a single reagent immunoassay for the qualitative detection of antibodies to human immunodeficiency virus types 1 and 2 (HIV-1 and HIV-2), in human blood. One step Anti-Syphilis Test is a rapid direct binding test for the visual detection of anti-syphilis in serum/plasma/whole blood as an aid in the diagnosis of syphilis infection. Test results are read visually without any instrument. It is based on the principle of double antigen sandwich immunoassay for determination of syphilis antibodies in serum/plasma/whole blood. Purified recombinant syphilis antigens are employed to identify anti-Syphilis antibodies specifically.
