HelpTest ID FPHIV Phenosense HIV Drug Resistance Replication Capacity
Useful For
Determines viral phenotype resistance to three classes of commonly prescribed antiretroviral drugs: nucleoside reverse transcriptase inhibitors (NRTI), non-nucleoside reverse transcriptase inhibitors (NNRTI), and protease inhibitors (PI). Viral replication capacity is also included.
Method Name
Polymerase chain reaction (PCR) amplification and viral culture
Reporting Name
Phenosense HIVSpecimen Type
Plasma EDTAOrdering Guidance
This procedure should be used for patients with documented HIV-1 infection and viral loads ≥500 copies/mL.
Specimen Required
Specimen Type: Plasma
Container/Tube: Lavender-top (EDTA) or plasma preparation tube (PPT)
Specimen Volumes: 3 mL
Collection Instructions: Draw blood into two 5-mL PPT (pearl top) or EDTA (lavender top) tubes. Centrifuge specimen within 6 hours of collection. Transfer plasma to one or more polypropylene screw-capped tube(s) and freeze. Freeze immediately. Send 3 mL plasma in a screw-cap vial frozen.
To avoid delays in turnaround time when requesting multiple tests, please submit separate frozen specimens for each test requested.
RECOMMENDED:
1. Patient's most recent viral load.
2. Viral load collection date.
NOTE:
1. Intended for use only for patients with viral loads greater than or equal to 500 copies/mL. For best results, viral loads should be confirmed within two weeks prior to submission for testing at Monogram.
2. Patient samples submitted <30 days apart are considered duplicate and will be canceled.
