Background: Blood transfusion is the most effective means of transmission of human immunodeficiency virus (HIV). The use of fourth-generation ELISA kits has significantly reduced the detection period of the viruses to its window period within 2–4 weeks. Objective: To analyze and compare the profile of blood donors who sero-converted to HIV positive. Materials and Methods: Blood donors reporting to the blood bank attached to a regional cancer center from January to December 2017 were included. The study was conducted in two phases. Phase 1 consists of random testing for HIV1/HIV2 reactive and nonreactive samples from clinical blood donors in the age group of 18–50 years. Phase 2 consists of confirmatory test with Western blot technique. Results: The fourth-generation kit confirmed 139 nonreactive out of 140 samples tested after running the samples with independent confirmatory test, whereas the third-generation ELISA test detected two HIV-reactive samples which were confirmed to be nonreactive by Western blot. Conclusions: For better clinical diagnosis and early detection of HIV, the use of fourth-generation test kits for screening of HIV infection is recommended.
