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.
PCR stands for Polymerase Chain Reaction, a method for amplifying DNA in vitro. Where, in cloning DNA into a plasmid, the DNA is amplified by the bacterial cell when it replicates the plasmid, PCR amplifies DNA in a test-tube.
