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, the result is interpreted in the context of cycle timing and the clinical question being asked.
About Progesterone Level Lab Test (Blood) in Altadena
Progesterone measurement is used to assess ovulation, luteal function, and hormonal balance.
In a natural menstrual cycle, progesterone remains low before ovulation, then rises sharply in the luteal phase as the corpus luteum forms. A level drawn at the expected mid-luteal point can provide evidence that ovulation occurred and that the corpus luteum is functioning.
Progesterone also supports early pregnancy by helping to maintain the uterine lining. Clinicians may order the test to monitor progesterone supplementation or to evaluate recurrent pregnancy loss, though results are always interpreted alongside other clinical findings.
The test is a standard immunoassay performed on a blood sample, typically serum or plasma. Results are reported as a concentration, and reference ranges vary by laboratory, by cycle phase, and by whether the patient is pregnant, so the lab's own range should be used for interpretation.
