HIV-1 and HIV-2 Antibody Confirmation and Differentiation, Prenatal, Plasma
Use
This test is used for confirmation and differentiation of HIV-1 and HIV-2 antibodies in plasma specimens from prenatal patients who show reactive results with 3rd- and 4th-generation HIV serologic assays. It plays a crucial role in determining the presence of HIV-1 and HIV-2 infections, aiding healthcare providers to make accurate diagnoses and treatment plans. However, this test is not intended as a screening test for HIV infection in symptomatic or asymptomatic individuals or as a confirmatory test for blood donor specimens.
Special Instructions
Not provided.
Limitations
A negative result for both HIV-1 and HIV-2 antibodies does not rule out acute HIV infection. All positive results should be verified with a second specimen. Participation in HIV-1 vaccine studies may lead to cross-reactivity. Assay performance not established for heat-inactivated specimens, cadaveric specimens, or samples with particulate matter.
