Progesterone normal value reference range, need to be judged according to the ovarian cycle, picture for reference. Due to the different ovarian cycle, the normal value reference range of progesterone, there is also a significant difference. In the follicular stage, the normal value reference range of progesterone is 0.6~1.9nmol/L.

If the test value of progesterone is increased, it may be due to physiological changes caused by pregnancy.
