What are the diagnostic criteria for bacterial vaginosis?

Bacterial vaginitis is a common type of vaginitis in clinical practice, which is mainly manifested by increased vaginal discharge with a foul odor, and may be accompanied by mild vulvar itching or burning sensation. So how to diagnose bacterial vaginitis? What are the diagnostic criteria for bacterial vaginitis? Let our experts introduce it to you in detail below.

1. Vaginal discharge is grayish white, very sticky, even like paste, and uniform, but it is not purulent, and the amount is variable.

2. The secretion has a particularly high amine content, so it has a fishy smell. During sexual intercourse or after activity, the smell is often aggravated due to the release of amines. Adding 10% potassium hydroxide to the secretion can also release the amine smell.

3. The pH value in vaginal secretions increases, with a pH range of 5.0 to 5.5, while the normal pH is 3.7 to 4.5.

4. Clue cells can be detected in wet smears of vaginal secretions.

Among the above four criteria, the diagnosis can be confirmed if three or more are met, and the fourth is emphasized as a necessary diagnostic criterion.
