Search Links: General Info : Protocols : LabTestsOnline

DescriptionLaboratory testing of HVS is often unnecessary. Use HVS for the investigation of abnormal vaginal discharge when diagnosis using symptoms and signs has failed. (Investigate by clinical examination, clinical and sexual history, and vaginal pH, before sending an HVS) See https://www.gov.uk/government/publications/abnormal-vaginal-discharge-management-and-laboratory-diagnosis
IndicationSymptoms 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 with dyspareunia or dysuria or >60 Group B streptococcal screening in pregnancy
Additional InfoHVS specimens are inappropriate for ruling out Gonococcal infections or Trichomoniasis. Please send Aptima sample for STI screening. (See separate Tests and Tubes entry) Laboratory investigations are determined by the vaginal pH and other clinical details. Investigations may include: - culture for yeast, in recurrent Candidiasis - culture for Staph aureus and haemolytic Strep - culture for anaerobes The laboratory report indicates the presence or absence of organisms investigated
Concurrent TestsAnnual STI screening (Aptima sample) should also be offered to all 18-25 yr olds with abnormal vaginal discharge
