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 visually examines your external genitals for signs of infection. Next, your doctor places an instrument (speculum) into your vagina to hold the vaginal walls open so that he or she can examine the vagina and cervix. Your doctor may collect a sample of any vaginal discharge for examination under a microscope or to perform a vaginal culture test, if needed.
  • Send a sample of vaginal secretions for testing. For uncomplicated yeast infections, your doctor probably won't perform any lab tests. However, if you have recurrent yeast infections, your doctor may be able to prescribe more effective treatment if he or she knows the specific type of yeast that's causing the infection.
