Specimen Requirements
Specimen
Plasma, frozen
Volume
3 mL
Container
Lavender-top (EDTA) or plasma preparation tube (PPT™).
Collection
Collect specimen in two lavender-top (EDTA) tubes or two PPT™ tubes. Do not use green-top (heparin) tubes. Centrifuge specimen within six hours of collection. Transfer plasma to one or more polypropylene screw-capped tube(s) (not "pop-top" or "snap-cap") and freeze. Ship specimen frozen. To avoid delays in turnaround time, when requesting multiple tests on frozen samples, please submit separate frozen specimens for each test requested.

Causes for Rejection
PPT™ not centrifuged; insufficient volume; heparinized plasma; nonfrozen specimens
Test Details
Use
The PhenoSense Integrase® assay is a phenotypic resistance test used to determine the susceptibility of a patient's HIV to integrase inhibitors. Integrase inhibitors block HIV replication by preventing the virus from integrating into the host cell's DNA. Raltegravir (Isentress®) is the first approved drug in this class of HIV antiretroviral drugs.
Limitations
This procedure should be used for patients with documented HIV-1 infection and viral loads ≥500 copies/mL.
Methodology
Polymerase chain reaction (PCR) amplification and viral culture. PhenoSense Integrase® is a trademark of Monogram Biosciences®.
