Biomarker Reference · Progesterone Metabolites
Progesterone Metabolites (a-Pregnanediol, b-Pregnanediol) (Progesterone Metabolites) is a clinical biomarker used in adrenal-stress assessment. Progesterone is metabolised to pregnanediol isomers excreted in urine, which serve as a surrogate for progesterone production over the collection window. It is measured in 2 laboratory tests on BiomarkersLabs.com.
Progesterone is metabolised to pregnanediol isomers excreted in urine, which serve as a surrogate for progesterone production over the collection window. Because progesterone itself is not measured directly in dried urine, these metabolites are used to estimate luteal-phase progesterone activity. Levels vary markedly with cycle phase and are minimal outside the luteal phase and in postmenopausal women.
Progesterone metabolites are used to estimate luteal-phase progesterone production and to assess the oestrogen-to-progesterone balance in functional hormone assessment. As a urinary surrogate, the result reflects metabolism over the collection period rather than a single serum value, and cycle timing is essential for interpretation.
Reference ranges vary by laboratory and assay platform. Interpret in context of the issuing laboratory's stated range.
