Order Progesterone Level Lab Test (Blood)Progesterone is a steroid hormone produced primarily by the ovaries after ovulation and, during pregnancy, by the placenta. A progesterone level blood test quantifies the amount of this hormone circulating in the bloodstream at the time the sample is drawn. Because progesterone rises and falls in a predictable pattern across the menstrual cycle, a single measurement is interpreted in the context of cycle timing and the clinical question being asked.
About Progesterone Level Lab Test (Blood) in Napa
The progesterone level lab test is a quantitative immunoassay performed on a serum sample.
After ovulation, the ruptured follicle transforms into the corpus luteum, which secretes progesterone to prepare and maintain the uterine lining. Measuring progesterone helps confirm that ovulation has occurred and helps assess the adequacy of luteal function.
In early pregnancy, progesterone supports the endometrium until the placenta assumes hormone production. Clinicians may order the test to evaluate early pregnancy viability or to monitor progesterone supplementation during assisted reproduction protocols.
Results are reported as a concentration, typically in nanograms per milliliter. Reference intervals vary by laboratory and by the phase of the menstrual cycle, so values are always interpreted against the reporting lab's range and the patient's cycle history.
