Test Id : FPGT
Phenosense Combination HIV Drug Resistance Assay
Useful For
Suggests clinical disorders or settings where the test may be helpful
Determines viral phenotype and genotype resistance to three classes of commonly prescribed antiretroviral drugs: nucleoside reverse transcriptase inhibitors (NRTI), nonnucleoside reverse transcriptase inhibitors (NNRTI), and protease inhibitors (PI). Viral replication capacity is also included.
Method Name

Phenosense GT
Specimen Type
Describes the specimen type validated for testing
Plasma EDTA
Ordering Guidance
This procedure should be used for patients with documented HIV-1 infection and viral loads =500 copies/mL.
ORDER QUESTIONS AND ANSWERS
| Question ID | Description | Answers |
|---|---|---|
| Z2096 | Most Recent Viral Load | |
| Z2097 | Viral Load Collected Date |
Specimen Required
Defines the optimal specimen required to perform the test and the preferred volume to complete testing
Specimen Type: Plasma
Container/Tube: Lavender-top (EDTA) or plasma preparation tube (PPT)
Specimen Volume: 3 mL
Collection Instructions: Draw blood in either PPT (pearl top) or lavender-top (EDTA) tubes. Centrifuge specimen within six hours of collection. Remove plasma from cells immediately, and transfer specimen to a screw-capped, plastic vial. Freeze 3 mL of PPT plasma or EDTA plasma immediately, send specimen 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 2 weeks prior to submission for testing at Monogram.
2. Patient samples submitted <30 days apart are considered duplicate and will be cancelled.
Specimen Minimum Volume
Defines the amount of sample necessary to provide a clinically relevant result as determined by the testing laboratory. The minimum volume is sufficient for one attempt at testing.
1 mL
Reject Due To
Identifies specimen types and conditions that may cause the specimen to be rejected
| Other | PPT(TM) not centrifuged; quantity not sufficient for analysis; heparinized plasma; nonfrozen specimen; specimen exposed to repeated freeze/thaw cycles; specimen received in "pop-top" or "snap-cap" tube |
Specimen Stability Information
Provides a description of the temperatures required to transport a specimen to the performing laboratory, alternate acceptable temperatures are also included
| Specimen Type | Temperature | Time | Special Container |
|---|---|---|---|
| Plasma EDTA | Frozen | 14 days |

Reference Values
Describes reference intervals and additional information for interpretation of test results. May include intervals based on age and sex when appropriate. Intervals are Mayo-derived, unless otherwise designated. If an interpretive report is provided, the reference value field will state this.
A final report will be attached in MayoAccess.
PDF Report
Indicates whether the report includes an additional document with charts, images or other enriched information
Day(s) Performed
Outlines the days the test is performed. This field reflects the day that the sample must be in the testing laboratory to begin the testing process and includes any specimen preparation and processing time before the test is performed. Some tests are listed as continuously performed, which means that assays are performed multiple times during the day.
Sunday through Saturday
Report Available
The interval of time (receipt of sample at Mayo Clinic Laboratories to results available) taking into account standard setup days and weekends. The first day is the time that it typically takes for a result to be available. The last day is the time it might take, accounting for any necessary repeated testing.
Performing Laboratory Location
Indicates the location of the laboratory that performs the test
