Abstract

The first diagnostic kits utilizing the enzyme-linked immunosorbent assay (ELISA) technique were developed in mid-eighties, and since then, this technique has become an increasingly important tool for screening multiple samples of blood or serum for presence of antibodies to various infectious pathogens, especially human immunodeficiency virus (HIV) in blood banks. However, most of the commercial diagnostic kits currently available in the market are too expensive, hence not easily affordable in most Diagnostic Laboratories. We designed an ELISA kit for diagnosis of HIV and compared it with some of the commercial kits. We used blood samples from the blood bank at the National Public Health Laboratory Services (NPHLS) in Nairobi and from patients referred to the Kenya Medical Research Institute (KEMRI) for HIV screening. Two commercial kits were used, Wellcozyme HIV Recombinant kit and Recombigen (env & gag) HIV-1 EIA kit. Out of 1350 samples tested by Recombigen (env & gag) HIV-1 EIA kit, 419 (31.0% ) were positive while 421 (31.2% ) samples were positive by Wellcozyme HIV Recombinant kit. Our ELISA kit detected a total of 431 positive samples out of 1350 (31.9% ), which was almost identical to the results from the other kits. Our kit was nearly identical in terms of sensitivity and specificity to the other two commercial kits used in this study. Thus our ELISA system, which is much cheaper than the commercial kits currently available in the market, offers a more affordable system for routine HIV tests.
