The ARIESÂ® Group A Strep Assay is a real-time polymerase chain reaction (PCR) based qualitative in vitro diagnostic test for the direct detection of Streptococcus pyogenes (Group A Î²-hemolytic Streptococcus) in throat swab specimens from patients with signs and symptoms of pharyngitis.
Polymerase Chain Reaction (PCR) The polymerase chain reaction (PCR) is a technique widely used in molecular biology for analyzing and testing DNA. The DNA polymerase used to amplify a piece of DNA by in vitro enzymatic replication contributed to the name for this technology. The PCR process sets in motion a chain reaction in which the DNA template is exponentially amplified (copied).
