Blood Test Types

Note
This lab test can be purchased without a physician and drawn at a Quest Diagnostics location. A small draw fee of $ 8 will be applied at checkout. There are no other "hidden" fees unless noted on the lab test.
Doctor/Practitioner
Certain lab tests may come back in the "normal" range. Reference ranges do not always mean "optimal." Patients may still experience symptoms in the "normal" range. It is important to speak with a qualified health practitioner regarding normal vs optimal.
Currently, NY, NJ, and RI state laws prohibit direct-access testing. This lab test cannot be conducted at lab locations within these states at this time.

MSH - Melanocyte Stimulating Hormone

Alpha MSH is a 13 amino acid peptide (1665 kD) with serine at the N terminal end and amidated valine at the C terminal end. Alpha MSH is derived from pro-opiomelanocorticotropin, a precursor protein which contains within its structure, the sequence of ACTH, beta MSH and gamma MSH. The amino acid sequence of alpha MSH is identical to ACTH 1-13 in humans. Alpha MSH stimulates melanosome dispersion within dermal melanocytes and melanin biosynthesis within epidermal melanocytes. It also stimulates aldosterone synthesis. Plasma alpha MSH increases in humans with high fever due to endotoxin. Average plasma alpha MSH has been found higher in AIDS patients and also in obese men with insulin resistance.
