Melanocyte-stimulating Hormone (MSH)
Also known as: Alpha-Melanocyte-stimulating Hormone
Use
Melanocyte-stimulating hormone (MSH) is a peptide hormone that plays a role in skin pigmentation and adrenal gland function. In clinical research, it is investigated for its involvement in various physiological and pathological processes, including the modulation of inflammatory responses, energy homeostasis, and hormonal regulation. The test measures the plasma levels of MSH, which can provide insights into its potential role in different disorders, although the assay is primarily intended for research purposes.
Special Instructions
Contact LabCorp supply department for collection kit. Trasylol® kits are required for specimen processing and can be ordered through the PeopleSoft system (LabCorp N° 33328). Ensure the sample is correctly labeled with "Trasylol® Added" and send frozen to prevent delays.
Limitations
Results for this test are for research purposes only by the assay's manufacturer and are not validated for clinical diagnostic use. The performance characteristics of this product have not been established. Results should not be used as a diagnostic procedure without confirmation of the diagnosis by another medically established diagnostic product or procedure. Factors such as improper sample handling, labeled conditions, and interferences like hemolysis or lipemia may lead to inaccurate results.
