Diagnosis of genital infection may be made by clinical examination, clinical and sexual history and vaginal pH see: https://www.gov.uk/government/publications/abnormal-vaginal-discharge-management-and-laboratory-diagnosis
In some cases pH testing may indicate a sample should be taken or other demographic or clinical details may indicate the need for sampling.
Genital samples are indicated in patients where:
- Symptoms consistent with recurrent thrush, vaginal pH < 4.5
- Abnormal discharge NOT consistent with BV or TV, vaginal pH > 4.5
- Abnormal discharge in a patient who is > 60 years old or who has dyspareunia or dysuria Group B streptococcal screening in pregnancy
- Discharge in children <10
- Male discharge
Negative results will be issued as “No target pathogens identified” with further comment to define what organisms the swab has been cultured for.
Positive results will report the target organism identified with further comment to define all organisms the swab was cultured for.

Additional information
Order Comms is set up to specifically guide on the samples required for investigations. The Genito-Urinary page is set up in collections of presenting conditions. The samples listed within the collection should be sent to the laboratory for investigation. If pH testing is indicated the request will lead you through steps of an algorithm and advise on empirical treatment if a swab is not necessary. In no case should a pH be entered incorrectly as this could lead to missed pathogens.
