Test ID: GHIVR
HIV-1 Genotypic Drug Resistance Mutation Analysis, with Reflex to Phenotypic Drug Resistance Prediction, Plasma
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.
Collection Container/Tube: Lavender top (EDTA)
Submission Container/Tube: Plastic vial
Specimen Volume: 2 mL
Collection Instructions:
1. Spin down and separate plasma from cells within 6 hours of collection.
2. Freeze plasma immediately and ship specimen frozen on dry ice.
3. If shipment will be delayed for >24 hours, freeze plasma at -70 degrees C (up to 35 days) until shipment on dry ice.
Additional Information:
1. This test is intended to be used to monitor known HIV-positive infections. It is not intended for primary detection of HIV infections.
2. Specimens submitted for HIV-1 genotyping should contain > or =1,000 copies/mL of HIV-1 RNA.
3. Viral load results and date of viral load testing are required. Viral load must have been performed within last 14 days with results > or =1,000 copies/mL.
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.
