Tests and diagnosis

By Mayo Clinic Staff

To diagnose a yeast infection, your doctor may:

  • Ask questions about your medical history. This might include gathering information about past vaginal infections or sexually transmitted infections.
  • Perform a pelvic exam. Your doctor examines your external genitals for signs of infection. Next, your doctor places an instrument (speculum) into your vagina to hold the vaginal walls open to examine the vagina and cervix.
  • Test a sample of vaginal secretions. Your doctor may send a sample of vaginal fluid for testing to determine the type of fungus causing the yeast infection. Your doctor may be able to prescribe more effective treatment for recurrent yeast infections by identifying the type of fungus causing the infections.
