| aids serodiagnosis | Immunologic tests for identification of HIV (HTLV-III/lav) antibodies. They include assays for HIV seropositivity and HIV seronegativity (elisa, immunofluorescence, immunoblot, etc.) that have been developed for screening persons carrying the viral antibody from patients with overt symptoms of aids or aids-related complex. (12 Dec 1998) |
