The AV score is one of the routine leukorrhea tests that can be used to evaluate the cleanliness of vaginal discharge. When the AV score is 3, it represents mild AV, which means that you may be suffering from vaginitis and need to undergo further tests. Those who suffer from UTI usually have changes in the urethral discharge, such as may contain various germs and molds. The vaginal cleanliness test is a stained smear of the examiner’s vaginal secretions, which is done under a microscope to look at the number of white blood cells and the presence or absence of bacteria, etc., in the vaginal secretions produced by the smear. In clinical AV scoring criteria are AV score <3, indicating no AV; AV score 3~4, indicating mild AV; AV score 5~6, indicating moderate AV; AV score >6, indicating severe AV. When the AV score of 3 reaches the classification of mild AV or above, it is recommended to have further examination and receive professional treatment in time.
