Vaginitis is an irritation of the vulva or vagina. It is very common. Many women think any irritation of the vagina or vulva is caused by a yeast infection. Yeast infection is one cause of vaginitis.
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.
The polymerase chain reaction (PCR) is a technology in molecular biology used to amplify a single copy or a few copies of a piece of DNA across several orders of magnitude, generating thousands to millions of copies of a particular DNA sequence. Miniprimer PCR: uses a thermostable polymerase (S-Tbr) that can extend from short primers (smalligos) as short as 9 or 10 nucleotides. 2  This method permits PCR targeting to smaller primer binding regions, and is used to amplify conserved DNA sequences, such as the 16S (or eukaryotic 18S) rRNA gene.
