Test ID: HIVSP    
HIV Antigen and Antibody Prenatal Routine Screen, Plasma

Testing Algorithm Delineates situations when tests are added to the initial order. This includes reflex and additional tests.

This test begins with HIV-1/-2 antigen and antibody screen by chemiluminescence immunoassay. If the screen result is reactive, then HIV-1/-2 antibody confirmation/differentiation test by immunochromatographic method is performed at an additional charge.

 

If HIV-1/-2 antibody confirmation/differentiation test is negative for both HIV-1 antibody and HIV-2 antibody, or indeterminate/negative for HIV-1/HIV-2 antibody, or indeterminate/indeterminate for HIV-1/ HIV-2 antibody, then HIV-1 RNA prenatal will be performed at an additional charge.

 

The following algorithms are available in Special Instructions:

-HIV Prenatal Testing Algorithm, Including Follow-up of Reactive Rapid Serologic Test Results

-HIV Testing Algorithm (Fourth-Generation Screening Assay), Including Follow-up of Reactive Rapid Serologic Test Results

Specimen Type Describes the specimen type validated for testing

Plasma

Ordering Guidance

If specimen is from either autopsy or cadaver blood sources, the proper FDA-licensed assay is HV1CD / HIV-1 and HIV-2 Antibodies for Cadaveric or Hemolyzed Specimens, Serum.

 

New York State clients: This test should not be requested for maternal/newborn HIV screening on specimens originating in New York State, due to state regulatory requirements for expedited result reporting.
