Introduction
In general, a routine blood test report primarily examines pH value, vaginal cleanliness, fungi and trichomonas, amine test, and clue cells. Clinically, pH value is commonly used to indicate acidity or alkalinity. The normal vaginal pH value ranges from 4 to 4.5. Typically, if vaginal inflammation occurs, the pH value will rise. Note that before undergoing vaginal discharge testing, local hygiene and cleanliness should be maintained.
Under normal circumstances, a vaginal discharge test report primarily evaluates the following: pH value, vaginal cleanliness, presence of fungi and trichomonas, amine test, and clue cells. The specific analysis is as follows:
1. pH Value
Typically, pH values are used clinically to indicate acidity or alkalinity. The normal vaginal pH ranges from 4 to 4.5. A rise in pH value often indicates the presence of vaginal inflammation.
2. Vaginal Cleanliness
Vaginal cleanliness is one of the standard indicators in routine vaginal discharge examinations. It is generally classified into four grades: Grades I–II are considered normal, while Grades III–IV are abnormal and suggest vaginal inflammation.
3. Vaginal Microorganisms
Vaginal microorganisms include Gardnerella, anaerobic bacteria, trichomonas, and fungi. The presence of Gardnerella or anaerobic bacterial infection is usually indicated by a "＋", signifying infection.
4. Amine Test
The amine test involves washing the vagina with a 5% sodium gluconate solution when glucosuria is present, followed by testing with pH paper. If Gardnerella tests positive, this indicates bacterial vaginosis.
5. Clue Cells
Clue cells refer to epithelial cells coated with bacteria, typically indicating bacterial invasion within the cervical mucosa and suggestive of bacterial vaginosis. A positive clue cell result is also one of the diagnostic criteria for bacterial vaginosis.
Note: Before undergoing a vaginal discharge examination, it's important to maintain local hygiene and avoid sexual intercourse to prevent interference with test results.
