title: A case study of human immunodeficiency virus with positive seroconversion to negative.
abstract: This case study demonstrates a 36-year-old ex-intravenous drug user (IVDU) who had been initially tested positive for human immunodeficiency virus (HIV) twice using Enzyme Immunoassay (EIA) method (Particle agglutination, PA done), but a year later he was tested HIV-negative. The patient was asymptomatic for HIV and T helper cells (CD4) count remained stable throughout this period. In light of this case, there may be a need to retest by molecular methods for high risk category patients who were initially diagnosed HIV-positive, but later showing an unexpected clinical course, such as a rising or stable CD4 titre over the years.
