Test ID HVCOP HIV-1 and HIV-2 Antigen and Antibody Routine Screen, 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.


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 (HIP12 / HIV-1/HIV-2 RNA Detection, Plasma).


New York State clients: This test should not be requested for maternal or 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: Lavender top (EDTA)

Submission Container/Tube: Plastic vial

Collection Instructions:

1. Centrifuge blood collection tube per collection tube manufacturer's instructions (eg, centrifuge and aliquot within 2 hours of collection for BD Vacutainer tubes).

2. Aliquot plasma into a plastic vial.

Useful For

Screening for HIV-1 and HIV-2 infection in nonsymptomatic, nonpregnant individuals older than 2 years


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

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


If the following result types are obtained from the HIV-1/-2 confirmation/differentiation, HIV-1 RNA detection and quantification will be performed at an additional charge:

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

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