Progesterone 24.8ng/ml is normal during pregnancy. Progesterone production is pulsatile and fluctuates throughout the day. The normal range varies from unit to unit. It is generally accepted that greater than 20ng/ml or 60nmol/L are considered normal ranges. It is also important to combine HCG and ultrasound results to determine the development of the embryo. As long as the progesterone value is greater than 20ng/ml during pregnancy it is within the normal range. Many experts do not recommend routine progesterone level monitoring during pregnancy, but a low progesterone level may indicate the possibility of ectopic pregnancy, biochemical pregnancy, adverse pregnancy, or luteal insufficiency. A progesterone value of 24.8 ng/ml is considered normal, combined with ultrasound and other determinations of fetal condition.
