HIV-1 infection in early seroconversion stage missed by rapid or ELISA tests--two case reports. Indian Journal of Pathology & Microbiology. 2005 Jul; 48(3): 395-6http://imsear.searo.who.int/handle/123456789/73415Two cases of HIV-1 infection demonstrating lack of sensitivity of rapid and ELISA screening tests are being reported. The first case was that of a 23 years old female whose recent infection was picked up by ELISA (Tetra ELISA) test but missed by two rapid tests (Comb AIDS and HIV Tridot). The 2nd case presumably too in early seroconversion phase, was that of a 39 years old male. In this case ELISA test failed to diagnose the infection while the two rapid tests were found to be strongly positive.engAIDS Serodiagnosis --methodsAdultDiagnostic ErrorsEnzyme-Linked Immunosorbent AssayFalse Negative ReactionsFemaleHIV Antibodies --bloodHIV Infections --diagnosisHIV Seropositivity --diagnosisHIV-1 --immunologyHumansMaleTime FactorsCase Reports
