Many mothers encounter this situation: when they receive a hospital laboratory test report, they find that the progesterone data on it is significantly different from before, and the unit is also different, so they have doubts. So, what are the differences between different units of progesterone?
The commonly used units internationally are nmol/L and ng/mL. The conversion relationship between these two units is 1ng/mL, which is approximately 3.1 times the nmol/L. Due to different detection methods, the units may vary. The normal value of progesterone in female follicular phase is 0.6-1.9 nmol/L, during ovulation phase it is 2.40-9.40 nmol/L, and after ovulation it is 20.7-102.4 nmol/L. There are different reference values for female progesterone in different situations, which are divided into reference values for normal menstrual cycle progesterone in women, reference values for progesterone in pregnant women, and reference values for progesterone in menopausal women.
Progesterone is a female hormone that participates in the female menstrual cycle of humans and other animals, supporting pregnancy and embryo formation. Unpregnant women only secrete a large amount of progesterone from the corpus luteum of the ovary in the latter half of each menstrual cycle. The brain, liver, and adrenal glands also secrete. During pregnancy (starting from the third month), the placenta can also secrete a large amount.
For pregnant women, a low progesterone level can easily cause redness. Early pregnancy redness generally refers to a small amount of vaginal bleeding within 12 weeks of pregnancy, indicating the risk of miscarriage and ectopic pregnancy. The color of bleeding may be pink, red, or brown. If the blood appears brown, pregnant mothers don't need to worry too much. Brown blood indicates that bleeding has stopped, so it will oxidize into coffee color. Just rest more and avoid vigorous exercise.
