Bacterial Vaginosis - Diagnosis

The diagnosis is made by examining a wet smear under microscope or by culture. A sample of vaginal fluid is seen under a microscope either by staining or under a special lighting, to look for bacteria associated with Bacterial vaginosis.

  1. Vaginosis is diagnosed if any three of the following conditions are present:
    • A clear background.
    • Absence of lactobacilli.
    • Presence of numerous "clue cells" (bacteria’s that adhere to the squamous epithelial cells that line the vagina giving them a fuzzy border, hence called clue cells).
    • Presence of Gardnerella bacteria under the microscope.
  2. Characteristic Vaginal discharge
    • A characteristic fishy odor when a drop of vaginal discharge is mixed with a drop of 10% potassium hydroxide.
  3. Amine Test:
    • Shows raised vaginal pH when a narrow range indicator paper is used.(3)

Upon entering the Menopause stage, I found myself with reoccuring Bacterial Vaginosis. I took antibotics for over a years off and on and it still came back. Then I remembered that years ago a doctor recommended Betidine douche for a bacterial infection. I HIGHLY recommend you try it.
