Human Immunodeficiency Virus 1 (HIV-1), Quantitative, Real-time PCR (Graphical) With Reflex to HIV-1 PhenoSense GT® Plus Integrase

Also known as: HIV-1 Plasma Viremia, HIV-1 RNA by Real-time PCR, Quantitative, Reflex to PhenoSense GT® Plus Integrase, Viral Load

Clinical Use

Order Test

Use

Detect and quantitate HIV-1 in plasma with reflex to PhenoSense GT® Plus Integrase (at additional charge) if viral load is >500 copies/mL.

Special Instructions

Not provided.

Limitations

The assay has a dynamic range from 20 to 10,000,000 copies/mL. Results outside this range may not be quantified accurately. The use of green-top (heparin) tubes affects the integrity of the sample, leading to potential rejection. Repeat testing may be compromised if specimen volume is insufficient.
