Test Catalog

Test ID: GHIVS    
HIV-1 Ultrasensitive Genotypic Drug Resistance Mutation Analysis, Plasma

Specimen Type Describes the specimen type needed for testing

Plasma EDTA

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 or pink top (EDTA)

Submission Container/Tube: Plastic vial

Specimen Volume: 4.5 mL

Collection Instructions:

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 degrees C (up to 35 days) until shipment with dry ice.

Additional Information:

1. This test is intended to be used to monitor patients with known HIV-positive infections. It is not intended for primary detection of HIV infections.

2. Submit specimens from  patients who have had > or =200 copies/mL of HIV-1 RNA within the preceding 14 days.

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.
