Screening for sexually transmitted infections (STI)

Sexually transmitted infections (STI) are passed from one person to another through unprotected sex or genital contact. Testing for STI can be done through GPs or through the Sexual Health Clinic:

www.sexualhealthoxfordshire.nhs.uk

In conjunction with the sexual health clinics, OUH Microbiology tests for:

  • Chlamydia
  • Gonorrhoea
  • Candida
  • Trichomonas
  • Bacterial vaginosis
  • Herpes
  • Non-specific urethritis (in men)
  • HIV
  • Syphilis
  • Hepatitis B
  • Hepatitis C.

Specimen requirements

Samples should be transported to the laboratory as soon as possible. If specimen transport will be delayed, e.g. from primary care, specimens should be stored in a refrigerator until transported to the laboratory.

From GPs

  • Cervical, high and low vaginal swabs in liquid transport medium: used for investigation for bacterial pathogens and Candida (not Gonorrhoea)
  • Male urethral swabs: used for culture of bacterial pathogens and candida (not Gonorrhoea)
  • Molecular testing for Chlamydia, Gonorrhoea, Herpes and Trichomonas vaginalis
  • Molecular testing for Chalmydia: kits are available from Haematology stores.
  • Female genital samples: BD collection kit for endocervical specimens
  • Male urine: BD urine preservative transport kit, send first pass after holding urine for two hours
