Human Immunodeficiency Virus Types 1 and 2 (HIV-1/2) Antibody Differentiation, Supplemental
Ordering Recommendation
Use only when patient has a repeatedly reactive third- or fourth-generation HIV screen test result. This test discriminates between HIV-1 and HIV-2 antibodies.
New York DOH Approval Status
Specimen Required

Separate from cells ASAP or within 2 hours of collection. Transfer 1 mL serum or plasma into an ARUP standard transport tube dedicated only for HIV testing. (Min: 0.5 mL) Remove particulate material.
Frozen.
Specimens containing particulate material. Severely hemolyzed or heat-inactivated specimens.
After separation from cells: Ambient: 48 hours; Refrigerated: 7 days; Frozen: 8 months (avoid repeated freeze/thaw cycles)

FDA
Note
For use ONLY when patient has a repeatedly reactive third- or fourth-generation HIV screen test result. This test discriminates between HIV-1 and HIV-2 antibodies. Results for each type are reported. This test is for use as the antibody differentiation test in the specific multitest algorithm. If results are negative or indeterminate, this test does NOT reflex to a nucleic acid test.
A multitest algorithm is recommended by the Centers for Disease Control and Prevention (CDC) and the Clinical Laboratory Standards Institute (CLSI) for the diagnosis of HIV (refer to https://arupconsult.com/content/human-immunodeficiency-virus).
