Test ID: HV1CM    
HIV-1 and HIV-2 Antibody Screen for Hemolyzed Specimens, Serum

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 antibody enzyme immunoassay (EIA). If HIV-1/-2 antibody EIA is reactive, then HIV antibody confirmation/differentiation by immunochromatographic method is performed at an additional charge.


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

Specimen Type Describes the specimen type validated for testing


Ordering Guidance

1. This test is not intended for testing symptomatic individuals (ie, diagnostic purposes). For testing hemolyzed specimens from such patients with or without risk factors for HIV infection, order HV1CD / HIV-1 and HIV-2 Antibodies for Cadaveric or Hemolyzed Specimens, Serum.

2. 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.

Additional Testing Requirements

If the initial enzyme immunoassay (EIA) result is negative and this test was ordered as a follow-up evaluation of a specimen with a reactive rapid HIV antibody test result, clients must call 800-533-1710 or 507-266-5700 to request supplemental testing for HIV antibody confirmation/differentiation by immunochromatography (HIVDI). The HIVDI / HIV-1 and HIV-2 Antibody Confirmation and Differentiation, Serum test is not FDA-approved for testing cadaveric specimens. If performed, test results will be reported with a disclaimer.
