1 The normal vaginal pH is 3.8 to 4.5. Bacterial vaginosis, trichomoniasis, and atrophic vaginitis often cause a vaginal pH higher than 4.5.  Whiff test. Several drops of a potassium hydroxide (KOH) solution are added to a sample of the vaginal discharge.
The pH of the vagina is quite acidic, averaging around 4.5 on the pH scale (7 is neutral). That's about as acidic as beer or tomatoes. Busy microbe communities in the vagina maintain this acidity. For example, lactobacillus, a group of lactic acid-producing bacteria, dominates the ecosystem in many women's vaginas.
