HIV1 RNA Quantitation
General Information
Lab Name
HIV1 RNA Quantitation
Lab Code
HRTABB
Epic Name
HIV1 Rna Quantitation
Description
The UW Clinical Virology Laboratory in the Department of Laboratory Medicine and Pathology incorporates the FDA approved Roche cobas® HIV-1 quantitative assay for the detection and quantitation of human immunodeficiency virus type 1 in EDTA plasma using real-time PCR amplification.
The range of quantitation of HIV-1 RNA is 20 to 10,000,000 copies/mL (33 to 1.67 x 107 International Units/mL).
The Roche cobas® HIV-1 quantitative assay uses primers specific for the HIV-1 gag gene and the HIV-1 LTR region (dual target).

Guidelines
Ordering & Collection
Specimen Type
Collection
Blood: EDTA plasma or PPT
Unacceptable: plasma from GREEN TOP (Heparin), YELLOW (ACD) or GRAY (Oxylate) and serum (No RED TOP)
Handling Instructions
Freshly drawn whole blood may be stored and/or transported for up to 24 hours at 2°C to 25°C prior to plasma preparation through centrifugation.
Quantity
requested: 2.0 mL plasma
minimum: 0.75 mL plasma
Processing
Blood: Centrifugation upon arrival, remove plasma from cells.
Plasma may be stored and/or transported:
- 2°C to 8°C for up to 6 days
- -18°C ± 2°C for up to 12 weeks
Outside Laboratory: Freeze at -10°C or colder and ship on dry ice. If freezer and/or dry ice is unavailable, ship immediately at 2-8°C (ice pack). Samples may be stored at 2-8°C (ice pack) for up to 48 hours of collection. Shipment time must not exceed 48 hours from collection if stored at 2-8°C. Samples stored at 2-8°C greater than 48 hours old may be rejected. Do not freeze/thaw.
