Serotonin Blood Test

Maryland rates for HCPCS 84260

This blood test measures the level of serotonin, a chemical messenger involved in mood, digestion, and blood vessel function. Elevated levels can be a sign of certain rare hormone-producing tumors, so this test is often used alongside other studies when a doctor suspects one of these tumors. It's typically ordered together with a related urine test that looks for a breakdown product of serotonin.
