ABSTRACT
The purpose of this study was to investigate the significance of the algorithm and results of transfusion transmitted infection tests in blood donor. Screening test results of the 10454 blood donor samples were evaluated the intra-assay correlations among the initial reactive and repeat screening results used in a third-generation enzyme-linked immunosorbent assays (ELISA, SD) for hepatitis B virus (HBV), hepatitis C virus (HCV). and HIV in blood samples. The initial reactive test results was positive 645 (6.2%) for HBV, 409(3.9%) for HCV, and 51(0.5%) for HIV however; repeat results was determined positive using the algorithm as follows: 462(4.4%) HBV, 341(3.3%)HCV, and 11(0.1%) HIV. Repeat screening HBV positive results was down until 4.4%, HCV 3.3% and WW 0.1% cumpairtt) with the initial results. As a result, false positive was determined I .X% for HBV, 0.6% for HCV, and 0.4% for HIV by initial reactive screening tests. The results of this study show that the implementation of the testing algorithm in blood transfusion services has a positive implication and reduces false positive rates in donors bloods.
