Introduction
Progesterone level of 18 ng/mL: If a woman is not pregnant, the normal value during the follicular phase is less than 3.18 ng/mL, and during the luteal phase it typically ranges from 16 to 63 ng/mL, which is considered normal. However, if a woman is pregnant, the normal range for progesterone in early pregnancy is between 63.4 and 1500 ng/mL. A progesterone level of 18 ng/mL during pregnancy is considered low and abnormal.
Whether a progesterone level of 18 ng/mL is normal depends on whether the individual is pregnant. The specific analysis is as follows:
1. Normal
If a woman is not pregnant, the typical progesterone level during the follicular phase is less than 3.18 ng/mL, while during the luteal phase it usually ranges from 16 to 63 ng/mL. Therefore, a progesterone level of 18 ng/mL is considered normal and does not require special treatment.
2. Abnormal
If the woman is pregnant, the normal range for progesterone is 63.4–94.5 ng/mL in early pregnancy, 95–150 ng/mL in the second trimester, and generally 150–1500 ng/mL in the third trimester. A progesterone level of 18 ng/mL during pregnancy is considered low and indicates an abnormal condition, commonly caused by inadequate luteal function.
Patients with low progesterone levels may be treated under medical supervision using medications such as progesterone capsules, dydrogesterone tablets, or medroxyprogesterone acetate tablets.
