Synonyms
- Cell-associated Viral DNA
- HIV-1 Genotype
- Resistance Analysis
Expected Turnaround Time
16 - 22 days
Turnaround time is defined as the usual number of days from the date of pickup of a specimen for testing to when the result is released to the ordering provider. In some cases, additional time should be allowed for additional confirmatory or additional reflex tests. Testing schedules may vary.

Specimen Requirements
Specimen
Whole blood, frozen
Volume
8 mL
Container
Lavender-top (EDTA) tube
Collection
Collect specimen in two lavender-top (EDTA) tubes. Do not centrifuge. Ship frozen. To avoid delays in turnaround time when requesting multiple tests on frozen samples, please submit separate frozen specimens for each test requested.
Storage Instructions
Freeze.
Causes for Rejection
Quantity not sufficient for analysis; heparinized plasma; nonfrozen specimen
Test Details
Use
Detect resistance of HIV-1 to protease, reverse transcriptase, and integrase inhibitors (GenoSure Archive®) and detect HIV-1 coreceptor tropism (Trofile® DNA) in cell-associated viral DNA; determine eligibility for CCR5 antagonist therapy, such as maraviroc (Selzentry®).
Limitations
This procedure should be used for patients with documented HIV-1 infection and undetectable viral load or low level viremia.
This test was developed and its performance characteristics determined by Labcorp. It has not been cleared or approved by the Food and Drug Administration.
Methodology
GenoSure Archive®: Polymerase chain reaction (PCR) amplification and next generation DNA sequencing
Trofile® DNA: Polymerase chain reaction (PCR) amplification and viral culture.
