Test Code HIVSS HIV-1 and HIV-2 Antigen and Antibody Routine Screen, Serum


Ordering Guidance


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 which is the US Food and Drug Administration-approved assay for these specimen types.

 

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 test pregnant individuals. For testing such patients, order HVPRS / HIV Antigen and Antibody Prenatal Routine Screen, Serum.

 

Screening, supplemental or confirmatory serologic tests for HIV-1 or HIV-2 antibodies cannot distinguish between active neonatal HIV infection and passive transfer of maternal HIV antibodies in children up to 2 years. Diagnosis of HIV infection in newborns and children up to 2 years should be made by virologic tests, such as detection of HIV RNA (HIS12 / HIV-1/HIV-2 RNA Detection, 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.

Reflex Tests

Test ID Reporting Name Available Separately Always Performed
HIVDI HIV Ab Confirm / Differentiation, S Yes No
HIS12 HIV-1/HIV-2 RNA Detect, S Yes No

Testing Algorithm

This test begins with HIV-1/-2 antigen and antibody (Ab) screen by electrochemiluminescence 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
