Term Description

Test is a rapid enzyme immunoassay used as a diagnostic aid for the detection and differentiation of HIV-1 and HIV-2 antibodies in serum or plasma. This code is based on, but not limited to, BIO-RAD's Multispot HIV-1/HIV-2 Rapid Test, which was approved in June of 2012 by the FDA for distinguishing HIV-1 from HIV-2 and is being considered as a replacement for Immune blot for the confirmation of positive HIV EIA tests by routine methods. It takes approximately 15 minutes to complete.

Part Description

LP36650-7   HIV 1 & 2
Human immunodeficiency virus (HIV) is categorized into two types, HIV-1 and HIV-2. Worldwide, most HIV infections are HIV-1, whereas HIV-2 largely has been confined to persons in or from West Africa (1,2). HIV-1 and HIV-2 have the same routes of transmission, and both can cause acquired immunodeficiency syndrome (AIDS) (3); however, HIV-2 infections should be differentiated from HIV-1 infections because they are less likely to cause AIDS and their clinical management differs (4,5). CDC's current surveillance case definition for HIV infection applies to both variants of HIV (6) but lacks criteria for differentiating between HIV-1 and HIV-2.

To enumerate and describe HIV-2 cases reported in the United States, a working case definition was developed. During 1988 through June 2010, a total of 242 HIV-2 cases were reported to CDC. Of these, 166 met the working definition. These HIV-2 cases were concentrated in the Northeast (66%, including 46% in New York City) and occurred primarily among persons born in West Africa (81%). Ninety-seven of the HIV-2 cases also had a positive HIV-1 immunoblot antibody test result (e.g., Western blot). Immunoblot antibody tests currently used to confirm HIV reactive screening tests do not contain reagents specific to HIV-2 and thus are not reliable for identification of HIV-2 infections (7). Additional testing specific to HIV-2 should be considered if HIV-1 test results are atypical or inconsistent with clinical findings, especially for persons from West Africa. If an HIV case is reported to the health department but subsequently identified as HIV-2, health-care providers should update the case report to reflect the correct type. As of June 2012, the Bio-Rad Multispot HIV-1/HIV-2 Rapid Test is FDA approved for distinguishing HIV1 from HIV2. Source: Centers for Disease Control and Prevention, LV Torian, et al.

Change Reason
The EIA method, which was always intended to cover more than just enzyme-linked immunoassay and whose display name for the long common name has always been Immunoassay, was renamed IA in order to eliminate ambiguity about whether the method has a broader meaning than just enzyme-linked immunoassay. Likewise, EIA.rapid was renamed IA.rapid. These changes were approved by the Laboratory LOINC Committee in June 2016.
