pH of vaginal fluid >4.5; Release of a fishy odor on adding alkali—10% potassium hydroxide (KOH) solution. At least three of the four criteria should be present for a confirmed diagnosis. [46] A modification of the Amsel criteria accepts the presence of two instead of three factors and is considered equally diagnostic. [47]
Transudate has a neutral pH, so increases in its production can temporarily shift vaginal pH to be more neutral. [4] Semen has a basic pH and can neutralize the acidity of the vagina for up to 8 hrs. [4] The composition and amount of vaginal discharge changes as an individual goes through the various stages of sexual and reproductive ...
Vaginal irrigation, tampon use or sex (potentially disrupting the vaginal pH) should be avoided for 24 hours before the test. Vaginal medicines (such as a nonprescription vaginal yeast medicine) should not be used during the 2 to 3 days before the test. [1] The sampling is done with the patient in lithotomy position.
Vaginal discharge is often misunderstood, but it plays a key role in keeping the vagina healthy.
Average vaginal pH is 7.0 in pre-pubertal girls. [145] Although there is a high degree of variability in timing, girls who are approximately seven to twelve years of age will continue to have labial development as the hymen thickens and the vagina elongates to approximately 8 cm.
