HIV Antigen and Antibody Prenatal Routine Screen, Serum
Use
This test is used for screening HIV-1 and HIV-2 infection in nonsymptomatic pregnant patients. It is not intended for use as a screening or confirmatory test for blood donor specimens. Routine screening begins with an HIV-1/-2 antigen and antibody screening test, typically performed by various FDA-approved assay methods, including rapid HIV antibody tests, enzyme immunoassays, and chemiluminescent immunoassays.
Special Instructions
If the specimen is obtained from either autopsy or cadaver blood sources, order HV1CD / HIV-1 and HIV-2 Antibodies for Cadaveric or Hemolyzed Specimens, Serum. This test is not for screening or testing symptomatic individuals. Specific state regulatory requirements should be checked when ordering for maternal/newborn screening in New York State.
Limitations
This test has not been licensed by the FDA for the screening of blood, plasma, cells, tissues, and cellular and tissue-based product donors. It is not diagnostic on its own and should be used in conjunction with supplemental tests for confirmation. False positives may occur in populations with low HIV prevalence. Performance characteristics have not been established for specimens that are grossly hemolyzed, lipemic, icteric, or heat-inactivated.
