Test ID HVPRS HIV Antigen and Antibody Prenatal Routine Screen, Serum


Ordering Guidance


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

 

This test should not be used to test symptomatic individuals (ie, diagnostic purposes). For testing such patients, order HIVDS / HIV-1 and HIV-2 Antigen and Antibody Diagnostic Evaluation, Serum.

 

This test should not be used to screen or test asymptomatic, nonpregnant individuals. For testing such patients, order HIVSS / HIV-1 and HIV-2 Antigen and Antibody Routine Screen, 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.

Testing Algorithm

This test begins with HIV-1/-2 antigen and antibody (Ab) 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 the following result types are obtained from the HIV-1/-2 confirmation/differentiation test, HIV-1/HIV-2 RNA detection will be performed at an additional charge:

-Negative for both HIV-1 Ab and HIV-2 Ab

-Indeterminate for HIV-1 Ab but negative for HIV-2 Ab

-Negative for HIV-1 Ab but indeterminate for HIV-2 Ab

-Indeterminate for both HIV-1 Ab and HIV-2 Ab

-Positive for both HIV-1 Ab and HIV-2 Ab
