Phenosense Combination HIV Drug Resistance Assay
Specimen Type Describes the specimen type needed for testing
Specimen Required Defines the optimal specimen. This field describes the type of specimen required to perform the test and the preferred volume to complete testing. The volume allows automated processing, fastest throughput and, when indicated, repeat or reflex testing.
Draw blood into two 5 mL PPT (pearl top) or EDTA
(lavender top) tube(s). Immediately centrifuge (within 2 hours of
collection) at 1000-1200 x g at room temperature for 10-15
minutes. Do not allow samples to remain in centrifuge after
centrifugation. Remove plasma from cells immediately and
transfer to a plastic screw cap tube. Freeze immediately.
Send 3 mL plasma in a screw-cap vial frozen.
- Patient's most recent viral load
- 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 cancelled.
Specimen Minimum Volume Defines the amount of specimen required to perform an assay once, including instrument and container dead space. Submitting the minimum specimen volume makes it impossible to repeat the test or perform confirmatory or perform reflex testing. In some situations, a minimum specimen volume may result in a QNS (quantity not sufficient) result, requiring a second specimen to be collected.

Anticoagulants other than
Warm reject; Cold reject
Specimen Stability Information Provides a description of the temperatures required to transport a specimen to the laboratory. Alternate acceptable temperature(s) are also included.
