Human Immunodeficiency Virus Types 1 and 2 (HIV-1/2) Antibody Differentiation, Supplemental, with Reflex to HIV-1 Quantitative NAAT, Plasma
Useful as a supplemental assay for repeatedly reactive third- or fourth-generation HIV screen tests, when following the CDC Proposed HIV Diagnostic Algorithm. This test cannot be used as a rapid screen nor as a follow-up for a positive rapid screen.
Qualitative Immunoassay/Quantitative Transcription-Mediated Amplification
Lavender (EDTA), or Pink (K2EDTA).
Separate from cells within 24 hours of collection. Transfer 3 mL plasma into an ARUP Standard Transport Tube dedicated only for HIV testing. (Min: 1 mL) Remove particulate material.
Serum. Heparinized or citrated plasma specimens. Specimens submitted in plasma preparation tube. Specimens containing particulate material. Severely hemolyzed or heat-inactivated specimens.
After separation from cells: Ambient: Unacceptable; Refrigerated:72 hours; Frozen: 3 months (avoid repeated freeze/thaw cycles)
Effective November 12, 2018
|3000867||Human Immunodeficiency Virus 1 (HIV-1) by Quantitative NAAT, Plasma||Not detected|
This test should not be used for blood donor screening, associated re-entry protocols, or for screening Human Cells, Tissues, and Cellular and Tissue-Based Products (HCT/P).
No compliance statements are in use for this test.
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 multi-test algorithm. It is not to be ordered as a rapid screen test and cannot be used as a supplemental test if the initial screen test was a rapid test.
If the HIV-1/ 2 Antibody Differentiation Immunoassay is Negative or Indeterminate, then the Human Immunodeficiency Virus 1 (HIV-1) by Quantitative NAAT, Plasma, will be added. Additional charges apply. Refer to Human Immunodeficiency Virus 1 (HIV-1) by Quantitative NAAT, Plasma (ARUP test code 3000867) for additional information regarding Performed or Reported times, Interpretive Data and Notes for the reflex test.
The multi-test 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://www.arupconsult.com/Topics/HIV.html).
