What is the purpose of collecting leucorrhea?

Generally speaking, as long as women pay attention to keeping themselves clean in their daily lives and clean their bodies every day, they will basically not suffer from any gynecological diseases. But there are always exceptions. Some women suffer from gynecological diseases for various reasons and have to undergo a series of treatments. For this kind of examination, the female's leucorrhea is often tested. What is the purpose of this practice? Let's take a look at it below.

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 there are any, 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.

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.
