What is the normal level of progesterone on day 21?
Typically, day 21 to 23 serum progesterone concentrations of more than 10 ng/mL indicate normal ovulation and concentrations below 10 ng/mL suggest anovulation, inadequate luteal phase progesterone production, or inappropriate timing of sample collection.
How do you read progesterone test results?
What do my test results mean?
- 0.1 to 0.3 ng/mL for prepubescent girls.
- 0.1 to 0.7 ng/mL in the follicular stage of the menstrual cycle.
- 2 to 25 ng/mL in the luteal stage of the menstrual cycle.
- 10 to 44 ng/mL during the first trimester of pregnancy.
- 19.5 to 82.5 ng/mL during the second trimester of pregnancy.
What level of progesterone indicates miscarriage?
Many studies have shown that low serum progesterone is associated with threatened miscarriage. Our group has validated a single serum progesterone cutoff of 35 nmol/L taken at presentation with a threatened miscarriage can differentiate women at high or low risk of subsequent miscarriage [14, 15].
What is a normal progesterone reading?
Progesterone level (ng/mL) Normal levels are less than 0.20 ng/mL. Keep in mind that results can vary between laboratories. If you’re unsure about your test results, contact your healthcare provider.
Can a pregnancy survive low progesterone?
How low progesterone affects pregnancy. We’re not sure how low progesterone affects pregnancy.

Does high progesterone mean viable pregnancy?
2011), Daily and colleagues found that the mean serum progesterone was significantly high for viable pregnancies (22.1 ng/ml) compared to non-viable pregnancies (10.1 ng/ml) and they concluded that a serum progesterone assay alone is predictive of pregnancy outcome specially during the first 8 weeks of gestation (Daily …
Does low progesterone always mean ectopic?
Low levels of this hormone are frequently associated with an abnormal pregnancy, such as an ectopic pregnancy or an impending miscarriage. However, progesterone levels alone do not always predict the location or mean the pregnancy is healthy and are not routinely used to diagnose ectopic pregnancy.
Can low progesterone lead to miscarriage?
Low progesterone in pregnancy is associated with miscarriage—the question is why. One theory is that levels that are too low could theoretically cause miscarriage if the uterus is not ready to support a pregnancy. In this case, it could be that the ovaries have problems producing enough progesterone.
