pH value of vaginal discharge

Secretion is female secretion, which is a mixture of vaginal mucosal exudate, cervical canal and uterine wall glandular duct secretions. Its production is related to the action of estrogen. Under normal circumstances, the quality and quantity of secretions change with the menstrual cycle. So what is the pH value of female secretions?

The pH value of secretions is to check the pH of female secretions, that is, the pH acidity and alkalinity. It is a new item in the basic routine examination of leucorrhea.

Standard value

When everything is normal, the pH is 4.5

Clinical manifestations

Abnormal results: When the pH exceeds 5-6, it indicates candidal or bacterial vaginitis. Groups that need to be checked: women with colored paste-like secretions, bean curd-like secretions, foam-like secretions, tofu-like secretions, and brown leucorrhea.

Frequently asked questions

Inappropriate groups: None. Taboos before the test: Sexual intercourse is strictly prohibited three days before the test. You should avoid eating after 8 pm the day before a routine physical examination. The test should be done 3-7 days after the menstrual period ends. Regulations during inspection: Inspection relieves stress. Inspection may cause stress to the body and mind, so you should respond proactively and cooperate closely with the inspection.

Check the whole process

Use a sterile cotton ball to collect a small amount of secretions from the posterior fornix of the vagina, place it on a slide filled with 1-2 drops of saline, and immediately perform a smear under a microscope.

Abnormal main manifestations

1. Cheese-like discharge or tofu-like leucorrhea-like discharge: It is candidal vaginitis, often accompanied by severe vulvar itching or burning pain.

2. The discharge is thinner, light green, sticky and has a foul odor, which is characteristic of candidal vaginitis and is accompanied by vulvar itching.

3. Grayish white, thin, fishy-smelling discharge is a characteristic of bacterial infection of the vagina, accompanied by mild itching in the private parts.

4. Tofu-like leucorrhea: slightly yellow or yellow-green, sticky, and often has an odor. It is caused by bacterial infection. This can be seen in gonorrhea Neisseria vaginitis, acute cervicitis and endocervicitis, vaginal cancer or cervical cancer with high incidence of concurrent infection. Uterine pyometra or foreign body residue in the female vagina can also cause leucorrhea with curd residue.

6. Brown leucorrhea: thinner vaginal discharge like water sample or rice water, with fishy smell, commonly seen in late stage cervical cancer, vaginal cancer or submucosal uterine fibroids with infection. Intermittent discharge of clear, yellow-red or reddish-brown leucorrhea should be considered as a possible cervical adenocarcinoma.

7. Bloody leucorrhea: The secretion is stained with blood, and the number of blood streaks varies. Cervical cancer, endometrial cancer, cervical cysts, cervical columnar epithelial cell disorder and infection, or uterine submucosal uterine fibroids should be considered. Insertion of an IUD can also cause bloody leucorrhea.
