Test ID HIVDS HIV-1 and HIV-2 Antigen and Antibody Diagnostic Evaluation, Serum

Ordering Guidance

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


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 infants during the postnatal period (up to 2 years old). Diagnosis of HIV infection in newborns and infants up to 2 years old 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.

Specimen Required

Supplies: Sarstedt Aliquot Tube, 5 mL (T914)

Collection Container/Tube: Serum gel

Useful For

Diagnosing HIV-1 and/or HIV-2 infection in symptomatic patients more than 2 years old


Follow-up testing of individuals with reactive rapid HIV test results


This test should not be used as a screening or confirmatory test for blood donor specimens.

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 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


The following algorithms are available:

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

-Meningitis/Encephalitis Panel Algorithm
