Progesterone, LC/MS
**Progesterone** is a key reproductive hormone involved in regulating the menstrual cycle, supporting early pregnancy, and balancing the effects of estrogen. In men, it also plays a role in testosterone metabolism and adrenal function. This test uses **liquid chromatography–mass spectrometry (LC/MS)** for ultra-sensitive and highly accurate measurement, especially valuable in cases requiring precise hormone monitoring.
