Includes
If HIV-1 RNA, Quantitative, PCR is ≥1000 copies/mL, then HIV-1 Coreceptor Tropism, Ultradeep Sequencing will be performed at an additional charge (CPT code(s): 87906).
Preferred Specimen
3 mL plasma collected in an EDTA (lavender-top) tube
Minimum Volume
2.5 mL
Other Acceptable Specimens
Plasma collected in: PPT potasium EDTA (white-top) tube
Instructions
Samples submitted in primary tube will be rejected.
Freshly drawn specimens (whole blood) may be stored at 2-25°C for up to 24 hours prior to centrifugation. Separate plasma from cells within 24 hours of collection by centrifugation and immediately transfer to a transport tube. Follow manufacturer's instructions for collection tube handling.

FDA Status
This test was developed and its analytical performance characteristics have been determined by Quest Diagnostics Infectious Disease. It has not been cleared or approved by the FDA. This assay has been validated pursuant to the CLIA regulations and is used for clinical purposes.
Setup Schedule
Set up: Mon-Sat; Report available: 2-4 days
Reference Range
| HIV-1 RNA, QN,PCR | Not detected | copies/mL | |
| HIV-1 RNA, QN, PCR | Not detected | Log copies/mL | |
Clinical Significance
This test is intended for use in conjunction with clinical presentation and other laboratory markers of disease progress for the clinical management of HIV-1 infected patients. The test can be used to assess patient prognosis by measuring the baseline HIV-1 RNA level or to monitor the effects of antiretroviral therapy by measuring changes in EDTA plasma HIV-1 RNA levels during the course of antiretroviral treatment. This test is not intended for use as a screening test for the presence of HIV-1 in blood or blood products or as a diagnostic test to confirm the presence of HIV-1 infection.
