Human Immunodeficiency Virus1 RNA Quantitative Real-Time PCR with Reflex to Genotyping : 0051660

Mnemonic: HIVQ GR

Methodology: Real-Time Polymerase Chain Reaction
Performed: Mon, Wed, Fri
Reported: 2-13 days
Specimen Required: Collect:  One 5 mL lavender (EDTA), pink (K2EDTA), or PPT.

Transport:  3 mL plasma, frozen. (Min: 2.5 mL) Submit specimen in an ARUP Standard Transport Tube.

Submit specimen according to Biological Substance, Category B, shipping guidelines.


Pediatric Collection/Transport:  

Submit specimen according to Biological Substance, Category B, shipping guidelines.


Remarks:  CRITICAL FROZEN. Prior to freezing, separate plasma from cells within two hours of collection.  Separate specimens must be submitted when multiple tests are ordered.

Unacceptable Conditions:  Serum. Polystyrene tubes. Heparinized or nonfrozen specimens.  Specimens exposed to repeated freeze/thaw cycles or submitted in a PPT tube (aliquot plasma prior to freezing).

Stability:  After separation from cells: Ambient: Unacceptable; Refrigerated: 12 hours; Frozen: 4 months
Reference Interval:
 
Test Number Components Reference Interval
0055598Human Immunodeficiency Virus 1 RNA Quantitative Real-Time PCR Not detected
0055670Human Immunodeficiency Virus 1, Genotyping By report

Interpretive Data: Refer to individual components.
Note: The test is intended for use in conjunction with clinical presentation and other laboratory markers as an indicator of disease prognosis.  This test is also used as an aid in assessing viral response to antiretroviral treatment as measured by changes in HIV-1 RNA levels.
 
If HIV-1 RNA Quantitative Real-Time PCR is greater than or equal to 3.0 log copies/mL, then HIV-1, Genotyping will be added.
CPT Code(s): 87536; if greater than or equal to 1000 copies/mL (3.0 log copies/mL), add 87901
