The Bacterial Vaginosis Swab checks a vaginal sample for Gardnerella vaginalis, the bacterium most often linked with bacterial vaginosis, for women with unusual discharge or odour, or who want confidential sexual health screening.
Bacterial vaginosis, often shortened to BV, is a common condition in which the usual balance of bacteria in the vagina changes. Protective lactobacilli fall and other bacteria, particularly Gardnerella vaginalis, increase. BV is not classed as a sexually transmitted infection, but it is more common in people who are sexually active, and it can come and go.
This test uses a vaginal swab, which you can usually take yourself in a private room at the clinic, to detect Gardnerella vaginalis. Many people with BV notice a thin, grey or white discharge with a fishy smell, especially after sex, while others have no symptoms at all. Testing is confidential and non-judgemental.
The price includes your swab taken at our Chiswick clinic, analysis at the Randox accredited laboratory, a review of your result with an Omnia practitioner, and a GP feedback report on request.
Your report shows whether Gardnerella vaginalis was detected. Because small amounts of Gardnerella can be present in people without BV, a positive result is read with your symptoms. A negative result makes BV less likely, but other causes of discharge, such as thrush, trichomonas or chlamydia, may need checking.
BV is usually treated simply with antibiotics, and your practitioner can advise you on next steps or on seeing your GP or a sexual health clinic. The window periods that apply to infections such as chlamydia or HIV do not apply in the same way to BV, as the test looks at the current balance of bacteria. A result like this is for discussion and context rather than diagnosis.
Avoid testing during your period if possible. For 48 hours beforehand, avoid vaginal creams, pessaries, lubricants and douching, and avoid sex if you can, as these can affect the sample. Tell us if you have taken antibiotics or antifungals in the last two weeks. We will show you how to take the swab, and a practitioner can take it for you if you prefer.
If you would like a wider check, our STI tests cover chlamydia, gonorrhoea and other infections, and your partner can find the male Gardnerella urine test on our page listing every blood test and price in Chiswick.

No. BV is a change in the natural balance of vaginal bacteria. It is more common in people who are sexually active, but it is not classed as an STI.
Yes. Most people take the swab themselves in a private room using simple instructions. A practitioner can take it for you if you prefer.
