Test Details
Methodology
Abbott Alinity m HIV-1 assay
Result Turnaround Time
3 - 7 days
Turnaround time is defined as the usual number of days from the date of pickup of a specimen for testing to when the result is released to the ordering provider. In some cases, additional time should be allowed for additional confirmatory or additional reflex tests. Testing schedules may vary.
Use
Detect and quantitate HIV-1 in plasma
Limitations
Assay range: 20−10,000,000 copies/mL
Specimen Requirements
Specimen
Plasma, frozen
Volume
2 mL
Minimum Volume
1.1 mL (Note: This volume does not allow for repeat testing.)
Container
Ship in a screw-cap polypropylene frozen transport tube or centrifuged PPT™ tubes.
Collection Instructions
Collect specimen in lavender-top (EDTA), PPT™, or yellow-top (ACD-A) tubes. Centrifuge specimen. If drawn in EDTA or ACD, the plasma must be transferred to a screw-cap polypropylene transport tube and frozen. If refrigerated, whole blood specimen may be held for 48 hours prior to centrifugation. If room temperature, whole blood specimen may be held for 24 hours prior to centrifugation. Plasma specimens may be stored at -20°C for 60 days. If longer storage is required, plasma specimens may be stored at -70°C or lower for 6 months. Ship frozen on dry ice. To avoid delays in turnaround time when requesting multiple tests on frozen samples, please submit separate frozen specimens for each test requested.
