HIV-1 and HIV-2 Antibody Screen for Hemolyzed Specimens, Serum
Use
This test is useful for screening cadaveric or hemolyzed serum specimens for HIV-1 and/or HIV-2 infection in nonsymptomatic patients. It is not designed to be a diagnostic test for individuals with symptoms of HIV or as a screening test for blood donors. Non-symptomatic individuals with or without risk factors for HIV can be screened. A reactive test suggests the presence of HIV-1 or HIV-2 infection, while a negative result usually indicates the absence of these infections.
Special Instructions
Not provided.
Limitations
The test may produce false-positive results in populations with low HIV prevalence. It cannot differentiate between active infection and passive antibody transfer in infants up to 2 years of age. It cannot distinguish between HIV-1 and HIV-2 reactivity, necessitating further testing. Performance characteristics are not established for lipemic, icteric, or particulate-containing specimens.
