Normal value of e2 in early pregnancy

When menstruation is delayed for more than one week, you may be pregnant. After pregnancy, you need to go to the hospital in time to establish a pregnancy care handbook to understand the development of the fetus. One of the examinations will show the value of e2, which is the content of estradiol in the female body. Too low will cause fetal maldevelopment. If it deviates too far from the normal value, it needs to be taken seriously. So, what is the normal level of estradiol in early pregnancy?

1. The estradiol content is different in different periods of female life. Generally speaking, before puberty, the content is generally 0-121pmol/L; in the follicular phase, the content is approximately between 37-330pmol/L; during the ovulation phase, it becomes 367-1835pmol/L and in the luteal phase, it changes to 184-881pmol/L.

2. The estradiol content will also change at different stages of a woman's ovulation period. Generally, it is 48-521 pmol/L in the preovulation period, 70-1835 pmol/L in the ovulation period, but changes to 272-793 pmol/L in the postovulation period.

3. The amount of estradiol will vary throughout the pregnancy. It will increase slightly in normal pregnancy and drop sharply after the placenta is delivered. In the early stage of pregnancy, it is generally 0-300 ng/L, in the middle stage of pregnancy, it is generally 1000-8000 ng/L, and in the late stage of pregnancy, it is generally 5000-27000 ng/L

Generally speaking, as long as there is no bleeding after pregnancy and the B-ultrasound shows that the embryo is developing normally, there is no need to delve too deeply into the specific content of estradiol. However, sometimes low estradiol levels are a precursor to certain serious diseases, such as ovarian dysfunction, premature ovarian failure, Sheehan's syndrome, etc., which require attention.

Experts remind that to check the normal value of estradiol, do not eat too greasy or high-protein food the day before blood drawing and avoid drinking large amounts of alcohol. The alcohol content in the blood will directly affect the test results. After 8 pm the day before the test, you should start fasting for 12 hours to avoid affecting the test results.
