Gardnerella vaginalis is a bacteria which is thought to be the cause of bacterial vaginosis. Despite being known about since the 1950s its role is still poorly understood, in part because it is very commonly found in women who are perfectly healthy. If the balance between lactobacilli and G.vaginalis is upset causing an excess of G.vaginalis then bacterial vaginosis may develop.
A positive result for Gardnerella vaginalis is only significant if there are also symptoms such as itching or discomfort of the vagina or vulva, and a vaginal discharge with a fishy odour.
This test looks for the presence of DNA from Gardnerella vaginalis and will report whether it is detected.
