The Serotonin, Serum test measures the level of serotonin in the blood, a neurotransmitter involved in mood regulation, sleep, appetite, and gastrointestinal function. While serotonin is primarily active in the brain and gut, measurable levels in the blood can reflect systemic serotonin activity.
This test is commonly used in the evaluation of certain neuroendocrine conditions, such as carcinoid syndrome, and may also be ordered in specific metabolic or gastrointestinal assessments. Results are interpreted in conjunction with clinical findings and other diagnostic tests, as blood serotonin levels do not directly reflect brain serotonin activity.
