HIV-1 RNA Patient Source, Plasma
Use
The test is useful for the detection and diagnosis of HIV-1 infection in acutely or early infected individuals, including infants under the age of 2, who are the source of blood or body fluid in an occupational exposure event. It serves as a vital tool for identifying HIV-1 RNA, especially in cases where serologic tests may be unreliable, such as in infants of HIV-infected mothers.
Special Instructions
Not provided.
Limitations
This test is not FDA-approved for screening blood or blood product donors. It should not be the sole criterion for clinical decisions, as viral load below 20 copies/mL does not indicate absence of HIV-1 replication. It is not reliable for quantifying HIV-1 group N and HIV-2 strains or group O strain discrepancies. The test is not suitable for plasma preparation tubes due to potential false-high results.
