3041700 Methodology and Reference range changes. Effective January 11, 2023

Methodology

Previous:Updated To:
Abbott RealTime HIV-1 system uses an in vitro reverse transcription-polymerase chain reaction (RT-PCR) assay for the detection and quantitation of the diverse group M subtypes A-H as well as group O and N isolates.
The lower limit of quantitation is 20 copies/mL (1.30 log copies/mL) and the upper limit of quantitation is 10,000,000 copies/mL (7.0 log copies/mL). The qualitative limit of detection is 20 copies/mL (1.30 log copies/mL). Specimens reported as DETECTED but <20 copies/mL contain detectable levels of HIV-1 RNA even though the viral load is below the limit of quantitation.
