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.
PCR is short for polymerase chain reaction and is a method we can use to clone sequences of DNA. We often want to clone these sequences a whole bunch (on the order of a billion copies of a single sequence!), so technology is obviously involved. This is how it works: DNA is collected from somewhere.
