Community nucleic acid testing
WebNational Center for Biotechnology Information WebThe potential use of nucleic acid probe technology for the diagnosis of Vaginitis/Vaginosis was explored in the mid-1990s with the development of a DNA probe assay. Several manufacturers have now developed nucleic acid amplification tests (NAAT) and panel assays using Polymerase Chain Reaction (PCR) which can detect multiple pathogens.
