This test begins with HIV-1/-2 antibody EIA. If HIV-1/-2 antibody EIA is reactive, then HIV-1/-2 antibody differentiation is performed at an additional charge. HIV-1 and HIV-2 antibody differentiation test begins with the Bio-Rad Multispot HIV-1/HIV-2 Rapid Test, with the following reflex testing. In specimens with indeterminate HIV-1 antibody but negative HIV-2 antibody results, HIV-1 antibody confirmation by Western blot is performed at an additional charge. In specimens with reactive or unreadable results for both HIV-1 and HIV-2 antibodies, HIV-1 antibody confirmation by Western blot and HIV-2 antibody confirmation are performed at additional charges. In specimens with negative HIV-1 antibody but reactive HIV-2 antibody results, HIV-2 antibody confirmation is performed at an additional charge.
This is the appropriate test for testing asymptomatic individuals.
This test is not appropriate for testing symptomatic individuals. For testing hemolyzed specimens from symptomatic patients (ie, diagnostic purposes) with or without risk factors for HIV infection, order HV1CD / HIV-1 and HIV-2 Antibodies for Cadaveric or Hemolyzed Specimens, Serum.

1. If the initial 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 Mayo Medical Laboratories at 800-533-1710 or 507-266-5700 to add supplemental testing for HIV-1/-2 antibody differentiation by membrane immunoconcentration (HIVDI).
2. The HV1WB / HIV-1 Antibody Confirmation by Western Blot, Serum test has not been FDA-approved for testing on cadaveric specimens; if performed, testing will be resulted with a disclaimer.
