Motilin, Plasma or Serum

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

Motilin is a 22 amino acid peptide produced primarily by the enterochromaffin cells (EC2 or M cells) in the intestine, duodenum and the jejunum. It is absent from the stomach and colon. Motilin accelerates gastric emptying and colonic motor activity. Motilin also stimulates the feeding response. It has no structural similarities with other gastrointestinal peptides. Motilin secretion can be stimulated by acid and a fat-rich meal. Motilin can increase the secretion of pepsin and causes increased intra-gastric pressure. Motilin also stimulates lower esophageal sphincter contraction. Motilin levels are suppressed by Calcitonin. Motilin has a short half-life of approximately five minutes.

Reference Values Describes reference intervals and additional information for interpretation of test results. May include intervals based on age and sex when appropriate.
