Preferred Specimen

"Plasma
5 mL"

Instructions

"Collect specimen in two lavender-top (EDTA) or two PPT™) tubes. Do not use green-top (heparin) tubes. Centrifuge specimen within six hours of collection. Transfer plasma to one or more screw-cap polypropylene transport 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.

"

Transport Container

"Lavender-top (EDTA) or plasma preparation tube (PPT™)
"

Transport Temperature

frozen

Specimen Stability

frozen--2 years

Reject Criteria (Eg, hemolysis? Lipemia? Thaw/Other?)

"PPT™ not centrifuged; insufficient volume; heparinized plasma; nonfrozen specimens; specimens exposed to repeated freeze/thaw cycles; specimen received in ""pop-top"" or ""snap-cap"" tubes.
"

Methodology
"Polymerase chain reaction (PCR) amplification and DNA sequencing. "

Limitations

"This procedure may not be successful when the HIV viral load is <500 copies/mL plasma. If there is insufficient virus to produce results, HIV-1 RNA quantitation will be performed to confirm viral load, and the procedure will be billed at the account's prevailing fee.
"

Clinical Significance

"Detect resistance of HIV-1 to protease, reverse transcriptase, and integrase inhibitors
