Transcription-Mediated Amplification (TMA)
Quest test code 16185, HIV-1 RNA Ql
Clinical significance:
An in vitro nucleic acid amplification test for the qualitative detection of human immunodeficiency virus type 1 (HIV-1) RNA. The test is intended to be used as an aid in diagnosis of HIV-1 infection. Detection of HIV-1 nucleic acid is indicative of HIV-1 infection, respectively. The presence of HIV-1 nucleic acid in the plasma or serum of individuals without antibodies to HIV-1 or HIV-2 is indicative of acute or primary HIV-1 infection. The HIV-1 Qualitative PCR may also be used as an additional test to confirm the presence of HIV-1 infection in an individual with specimens reactive for HIV-1 antibodies or antigens. The assay may also be used as an aid in the diagnosis of infection with HIV-1 in pediatric subjects and pregnant women. This assay is not intended to be used for monitoring patient status, or for screening donors of blood, plasma, or human cells, tissues, and cellular and tissue-based products (HCT/Ps) for HIV.
