Prostaglandin E2 (PG E2), Urine

Clinical Information Discusses physiology, pathophysiology, and general clinical aspects, as they relate to a laboratory test

Prostaglandins are fatty acids derived from arachidonic acid metabolism. They are closely related to the Thromboxanes and Leukotrienes. Prostaglandin E2 is derived mainly from Prostaglandin H2, and is metabolized to Prostaglandin F2a, A2, and Dihydroketo Prostaglandin E2. Prostaglandin E2 is excreted directly into the urine. Prostaglandin E2 is a potent vasodilator and also a stimulus for Renin release. Prostaglandin E2 release is stimulated by cholinergic and alpha adrenergic agents.

Prostaglandin E2 potentiates the actions of Histamine and Bradykinin causing pain and accumulation of edema fluid. It relaxes the circular muscle of the gut in opposition to ProstaglandinF2a, and also relaxes the lower esophageal sphincter. Prostaglandin E2 also causes accumulation of water and electrolytes in the lumen of the gut by stimulating their secretion. Elevated levels of Prostaglandin E2 have been detected in patients with the Watery Diarrhea Syndrome, neural crest tumors, pheochromocytomas, and other amine-peptide-secreting tumors. Prostaglandin E2 production and circulating levels are drastically suppressed by aspirin and indomethacin. Urine Prostaglandin E2 levels give an integrated picture of Prostaglandin E2 production over a 24 hour minimizing the effect of diurnal variation and episodic secretion.

Reference Values Describes reference intervals and additional information for interpretation of test results. May include intervals based on age and sex when appropriate. Intervals are Mayo-derived, unless otherwise designated. If an interpretive report is provided, the reference value field will state this.
