Abstract:
In France, the first sample for the initial diagnosis of HIV-1 infection must be tested with two antibody assays: one being an enzyme-linked immunosorbent assay. If one is positive, confirmation tests are performed. We evaluated the performance of initial diagnostic strategies based on the use of one versus two enzyme-linked immunosorbent assay tests, either an antigen-antibody test or a simple antibody assay. We found that a single antigen-antibody test was more efficient than a combination of the two tests.
