What is Gardnerella Vaginalis rRNA PCR Swab Test? (Background Information)

  • Gardnerella vaginalis, or G. vaginalis, is a bacterium most commonly associated with bacterial vaginosis or inflammation of the vaginal tract
  • The vagina normally contains a diverse population of microorganisms, including bacteria and fungi. These coexist harmlessly with one another and are in fact beneficial to maintaining the health of the vaginal tract
  • However, certain factors may lead to a disruption in the balance of the microorganism population within the vaginal tract. These include certain antibiotics, immune deficiencies, and sexual activity
  • G. vaginalis is thought to be transmitted through sexual intercourse. Once introduced in the vagina, it is capable of overgrowing and causing the unpleasant symptoms of bacterial vaginosis (BV)
  • G. vaginalis also exists asymptomatically in some women. The reasons these women are not affected by G. vaginalis remain unknown
  • The Gardnerella Vaginalis rRNA PCR Swab Test is a vaginal culture test to detect the presence of G. vaginalis. It does this by identifying genetic material possessed by G. vaginalis, which is not present in humans
