Private Gardnerella Testing in London
Gardnerella vaginalis is the most common bacterium associated with bacterial vaginosis (BV). While BV is not classified as a sexually transmitted infection, it can be triggered by sexual activity and causes symptoms including unusual vaginal discharge and a characteristic fishy odour. Testing identifies the bacterium so appropriate antibiotic treatment can be prescribed.
When do you need a test?
If you have unusual vaginal discharge, a strong or fishy odour, or if a previous BV treatment has not resolved symptoms. Also recommended if a sexual partner has been diagnosed with BV-related symptoms.
Why is it important?
Untreated BV can increase susceptibility to other STIs including HIV, chlamydia, and gonorrhoea. During pregnancy, BV is associated with premature birth and low birth weight. Accurate diagnosis ensures targeted treatment rather than empirical antibiotics.
Procedure
Preparing for the test
No special preparation needed. Avoid vaginal douching for 24 hours before the test.
During the test
A healthcare professional will take a vaginal swab. The procedure takes seconds and causes minimal discomfort.
Results
Results are typically available within 3 working days. Your doctor will contact you with results and treatment options if needed.
Symptoms
- Thin, grey or white vaginal discharge
- Strong fishy odour, especially after sex
- Vaginal itching or irritation
- Burning during urination
- May be completely asymptomatic
How does it spread?
Gardnerella is part of the normal vaginal flora but can overgrow when the vaginal pH balance is disrupted. While not strictly an STI, it is more common in sexually active women and can be associated with new or multiple sexual partners.
Our STI testing packages
We also offer comprehensive screening options covering all major sexually transmitted infections. All packages include a full Consultation with our sexual health expert doctors as well as testing and a prescription for treatment if required. These packages are the highly recommended option for those experiencing symptoms, to ensure you're going to be tested for the most appropriate infections to your clinical situation.

Choose the right level of screening for your needs. All packages include a private GP consultation.
Clinical Guidance: Most bacterial STIs are detected within 1-2 weeks of exposure. HIV testing is most accurate after 28 days, though our 4th generation tests can provide early detection from 10 days post-exposure.
If you are experiencing symptoms, we strongly recommend our Gold or Platinum packages for the most comprehensive evaluation and immediate treatment initiation.
