The range of the normal value of progesterone for women needs to be judged according to the age of the woman and whether she is pregnant: a. For pregnant women, the normal value of progesterone should be greater than 10 nmol/L. If it is less than this value, the possibility of miscarriage cannot be ruled out, and the pregnant woman needs to undergo regular progesterone testing and examination for a clear diagnosis. With the growth of the pregnancy cycle, the value of progesterone will increase significantly, and after reaching a certain period, it will maintain a stable growth level. Second, in women who are not pregnant normally, the normal value of progesterone is about 0.5-1.0nmol/L during the follicular phase, 0.9-12nmol/L during ovulation, and between 20-104nmol/L after ovulation. For menopausal women, progesterone values can appear to have a significant decrease.
