MSH Blood Test in San Diego, California

Same day and Affordable MSH Blood Test, Locations Nationwide

Request A Test offers this convenient and affordable MSH Blood Test in San Diego, CA. This test measures the level of Melanocyte Stimulating Hormone (MSH) in a blood sample. MSH is a group of hormones produced primarily by the pituitary gland, hypothalamus, and skin cells. Most MSH in the body is produced in response to exposure to ultraviolet (sun) light. MSH plays a key role in the production of melanin, the substance which provides pigmentation to the skin, hair, and eyes. Melanin also protects skin cells from damage by UV radiation. A number of other functions in the body rely on MSH including regulation of appetite, salt and water balance, and controlling inflammation.

Excessive MSH levels can be caused by disorders that impair the adrenal glands such as Addison's Disease. When adrenal function is lower than normal, the hypothalamus produces more adrenocorticotropic hormone (ACTH) in an attempt to stimulate the adrenal glands. ACTH breaks down into MSH and the elevated MSH levels cause an abnormal darkening of the skin. As a result, hyperpigmentation is a symptom of Addison's Disease and other adrenal disorders. MSH levels can also be elevated by other conditions such as pregnancy, taking birth control pills, and Cushing's Syndrome, a disease that causes excess ACTH production. 

MSH deficiency can be caused by damage to the pituitary gland or adrenal glands. Lowered levels of MSH can cause a lack of skin pigmentation which makes people more susceptible to sunburns and a higher risk of developing skin cancer.
