HIV-1 RNA, Qualitative, Real-Time PCR - HIV-1 Qualitative is an in vitro nucleic acid amplification test for the qualitative detection of human immunodeficiency virus type 1 (HIV-1) RNA in human serum and plasma by PCR. The test is intended to be used as an aid in diagnosis of HIV-1 infection.
While qualitative HIV-1 RNA assays are used primarily for diagnostic purposes, quantitative HIV-1 RNA assays are typi-cally used to help monitor disease progression and treatment eficacy.
Presence of HIV-1 or HIV-2 RNA in the plasma of patients without antibodies to HIV-1 or HIV-2 is indicative of acute or primary HIV-1 or HIV-2 infection. This assay may also be used as an additional test, when it is reactive, to confirm HIV-1 infection in an individual whose specimen is repeatedly reactive for HIV-1 and/or HIV-2 antibodies.
PrEP HIV-1 RNA, Qualitative Real-Time PCR - This assay is part of a multi-step algorithm for determination of HIV status in patients being considered for PrEP. In patients with negative or indeterminate HIV antibody results who have reported an HIV exposure-prone event and have had signs and symptoms of acute HIV within the prior 4 weeks, an ...
The HIV-1/HIV-2 Qualitative test detects the presence of HIV-1 and/or HIV-2 RNA, whereas the HIV-1 Quant Dx Assay and the HIV-1 Assay detect the presence of HIV-1 RNA. The intended use of the HIV-1/HIV-2 Qualitative test also extends to HIV-2 confirmation.
Might appear under several names: HIV-1 proviral DNA PCR, HIV-1 RNA qualitative, HIV-1 RNA PCR, or an HIV-1 NAT If negative, rule out acute infection in people with a reactive screen but a negative or indeterminate supplementary test. If a NAT is positive after reactive screen and a negative or indeterminate supplementary test, then the person is
Positive HIV-1 RNA results in the absence of detectable antibodies indicate acute infection; negative results are consistent with absence of HIV-1 infection. A negative HIV-1 RNA test may be followed with an HIV-2 DNA/RNA test if clinically warranted.

Human immunodeficiency virus type 1 (HIV-1) RNA can be measured using qualitative or quantitative techniques. Qualitative testing (commonly referred to as nucleic acid testing or NAT) is used as a screening test to identify HIV-infected individuals, such as screening possible blood donors.
