Which test is used to measure serum serotonin?

In general, testing for serotonin falls under routine blood examination. The specific analysis is as follows:

Serotonin is a neurotransmitter produced by the body, primarily composed of 5-hydroxytryptamine. It is a substance used by nerve cells to transmit signals to each other. Serotonin can influence appetite, hunger, sleep, libido, and mood. Increasing serotonin levels moderately through diet may improve sleep, promote calmness, reduce irritability, and induce feelings of pleasure, happiness, and greater joy. Typically, serotonin testing requires a blood draw and is one of the components of a routine blood test.

Patients are advised to prepare adequately before blood collection. If any discomfort occurs, it is recommended to inform the doctor promptly to avoid adverse reactions.
