How to conduct cervical mucus examination?

summary

Cervical mucus examination is to take cervical surface secretions for observation. Cervical mucus is a glycoprotein gel derived from the gland cells of cervical mucosa, which is affected by various ovarian hormones. Before ovulation, the cervical mucus was gradually increased by estrogen; After ovulation, it is gradually reduced by the influence of progesterone. How to conduct cervical mucus examination? Let's talk about it

How to conduct cervical mucus examination?

The 5th-7th day of menstruation: very few, thick, turbid, only a lot of white blood cells and unformed mucus can be seen in the dry specimen on the slide. Pre ovulation (follicular phase, about the 6th-8th day to the 14th day of the cycle): the amount increases gradually, the quality is thin and transparent, when raised high, it looks like egg white, the pulling force increases, it can be pulled to about 10cm, and the crystal develops from type III to type I.

In the late stage of ovulation (early luteal phase, from the 14th day to the 20th-22nd day of the cycle), the amount is less, the quality is thicker, the transparency is obviously reduced, and the crystal is fuzzy, showing type IV. There was ellipsoid on the outside of the crystalline zone. When the crystal disappeared, only the ellipsoid was seen in the premenstrual period (the 22nd-28th day of the cycle, that is, the middle and late luteal period): the mucus was thick, turbid, the viscosity increased, and the crystal disappeared completely. Only oval bodies arranged in rows were seen on the slide, and atypical crystals occasionally appeared 1-2 days before menstruation.

Pregnancy: the amount of mucus is small, and the quality is viscous and frozen. The process from type I to type VI can be seen, or the typical ellipsoid can last more than two weeks without menstruation. If you see atypical crystals during pregnancy, it indicates the possibility of threatened abortion. If there is a history of habitual abortion, there is no type I crystal after pregnancy, indicating a good prognosis of pregnancy.

matters needing attention

Patients should be forbidden to use vaginal drugs and hormone drugs before examination, in order to prevent the change of cell morphology from bringing difficulties to the diagnosis. Keep a normal diet and work and rest time. Don't stay up late. From the seventh day of the menstrual cycle to ovulation, we should check, in order to understand the morphological changes of cervical mucus crystal, the inspection time is long, we should pay attention to go to the hospital on time.
