For estradiol in early pregnancy, the normal reference range is roughly between 200-1000 picograms per milliliter and will vary from person to person.
During pregnancy, the normal estradiol level is usually between 200-1000 picograms per milliliter. However, due to the different health conditions of each individual, there will also be differences in fetal development. As a result, the level of estradiol in the early stages of pregnancy will also vary. However, as long as the estradiol level in a pregnant woman’s body is within the normal range and remains stable, it can usually indicate normal fetal development.
During pregnancy, in addition to blood tests such as blood HCG, progesterone and estradiol, ultrasound is also needed to dynamically observe the development and size of the embryo.
Regular checkups are needed during pregnancy, especially in the early stages of pregnancy, and any abnormalities, such as bleeding and abdominal pain, should be seen promptly.
