Is it necessary to use a dilator to check for leucorrhea?

Generally, a dilator is not needed when checking leucorrhea. This kind of examination instrument is mainly used for vaginal examination. The leucorrhea examination is to detect the bacteria and white blood cell index contained in the leucorrhea, so that you can know whether your leucorrhea is in an abnormal reaction. In addition, it is necessary to check the cleanliness of the vagina. This examination item is also more important. Only in this way can the examination be more comprehensive.

Use a sterile long cotton swab to take a small amount of leucorrhea from the posterior fornix, place it on a glass slide containing 1-2 drops of normal saline, and immediately examine it under a microscope.

Leucorrhea examination is a routine examination of vaginal discharge, including vaginal pH, vaginal cleanliness, microbial examination, amine test, and clue cell examination.

Abnormal results: Vaginal pH: The normal vaginal pH is between 4 and 4.5, which is weakly acidic and can prevent pathogenic bacteria from multiplying in the vagina. The pH of candidal vaginitis can be within this range. When suffering from trichomoniasis or bacterial vaginitis, the pH of leucorrhea increases and can be greater than 5-6.

Vaginal cleanliness: It is generally divided into four degrees. Generally, degrees I and II are normal, while degrees III and IV indicate vaginitis, that is, a large number of white blood cells or bacteria can be seen in the secretion picture. Microbiological examination: There will generally be items such as fungi, Trichomonas, and Neisseria gonorrhoeae. If present, the result will be indicated as “+”. Amine test: The leucorrhea of ​​patients with bacterial vaginosis may have a fishy odor, which is caused by the amines in the leucorrhea being volatilized after being alkalized with potassium hydroxide.

Clue cells: Clue cells are the most sensitive and specific sign of bacterial vaginosis. Clinicians can make a diagnosis of bacterial vaginosis based on a positive amine test and the presence of clue cells. People who need to be checked: women with colorless paste-like leucorrhea, bean curd-like leucorrhea, foamy leucorrhea, purulent leucorrhea, and watery leucorrhea.

First, gynecological examinations should be conducted away from the menstrual period, and it is best to choose the period between the end of menstruation and before ovulation to undergo a gynecological examination. Second, do not have sex the night before a routine gynecological examination, because the man’s semen and the spermicide on the condom may appear in the test sample the next day and interfere with the doctor’s judgment. Third, do not use any vaginal medications the night before a gynecological examination. Any medications for treating vaginal infections or lubricants will affect the test samples, cover abnormal cells, and affect the test results. The leucorrhea sample should be sent for examination immediately after being collected by the gynecologist without delay.
