Normal standard of leucorrhea routine examination

Routine examination of leucorrhea is a common examination method in gynecology today. Through leucorrhea examination, various types of gynecological diseases can be detected, so that women can have a clearer understanding of their health status. If there is a disease, it can be treated early to avoid the deterioration of the disease and posing a greater threat to women's health. Next, I will introduce to you the normal standards and other related knowledge of routine leucorrhea examination!

1. Inspection content

1. Vaginal pH

The normal vaginal pH is 4-4.5, which is slightly acidic and can prevent pathogenic bacteria from multiplying in the vagina.

2. Vaginal cleanliness

Vaginal cleanliness can be divided into 4 levels: Level I: A large number of vaginal epithelial cells and vaginal bacilli can be seen under a microscope. Grade II: Vaginal epithelial cells, a small amount of white blood cells, some vaginal bacilli, and a small amount of miscellaneous bacteria or pus cells are seen under the microscope. Grade III: A small amount of vaginal bacilli, a large number of pus cells and miscellaneous bacteria are seen under the microscope. Grade IV: No vaginal bacilli are seen under the microscope, and except for a small amount of epithelial cells, there are mainly pus cells and miscellaneous bacteria. Grades I to II are normal, and grades III to IV are abnormal leucorrhea, indicating vaginal inflammation.

3. Vaginal Microbiome

Normal situation: None. There will usually be items such as fungi, trichomonas, and gonococci. If present, it will be marked as “+” (positive) on the result, and if not, it will be marked as “-” (negative).

4. Amine test is also called amine odor test

It is a method for diagnosing bacterial vaginosis. If you suffer from bacterial gynecological inflammation, your leucorrhea may have a fishy odor, because the amines produced by anaerobic bacteria release ammonia when they come into contact with potassium hydroxide.

5. Clue Cells

It is the most sensitive and specific sign of bacterial vaginosis. The diagnosis of bacterial vaginosis can be made based on a positive amine test and the presence of clue cells.

2. Clinical Significance

1. When the vaginal pH value is >5-6, it may be trichomoniasis or bacterial vaginitis.

2. When the vaginal cleanliness is grade III to IV, it may indicate vaginitis.

3. Vaginal microbiological examination shows positive results for Candida and Trichomonas, which may indicate vaginitis.

4. If the leucorrhea is abnormal, such as yellow or yellow-green with a foul odor, it may be Trichomonas vaginitis; if the leucorrhea is like tofu dregs, it may indicate fungal vaginitis.

3. Notes

The following situations will affect the results of leucorrhea examination and should be avoided.

1. Avoid sexual intercourse within 24 hours before the leucorrhea examination.

2. Avoid taking a bath, vaginal douching, or applying topical medication before the examination.

3. It is not advisable to check leucorrhea before or after menstruation, during pregnancy, or after taking estrogen drugs.
