To diagnose vaginitis, your doctor is likely to:

  • Review your medical history. This includes your history of vaginal or sexually transmitted infections.
  • Perform a pelvic exam. During the pelvic exam, your doctor may use an instrument (speculum) to look inside your vagina for inflammation and abnormal discharge.
  • Collect a sample for lab testing. Your doctor might collect a sample of cervical or vaginal discharge for lab testing to confirm what kind of vaginitis you have.
  • Perform pH testing. Your doctor might test your vaginal pH by applying a pH test stick or pH paper to the wall of your vagina. An elevated pH can indicate either bacteria vaginosis or trichomoniasis. However, pH testing alone is not a reliable diagnostic test.
