HIV-1 Genotypic Drug Resistance Mutation Analysis, 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
1. Spin down and separate plasma from cells within 6 hours of draw.
2. Freeze specimen immediately, and ship frozen on dry ice.
3. If shipment will be delayed for >24 hours, freeze specimen at -70 C (up to 35 days) until shipment on dry ice.
1. 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.
2. This test is intended to be used to monitor known HIV-positive infections. It is not intended for primary detection of HIV infections.
3. Specimens submitted for HIV-1 genotyping should contain > or =1,000 copies/mL of HIV-1 RNA.
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.
