Serotonin Levels

Meaning

The measured concentration of the monoamine neurotransmitter serotonin (5-hydroxytryptamine or 5-HT) in the blood or cerebrospinal fluid, reflecting its availability and activity within the central nervous system and peripheral tissues. Serotonin is integral to regulating mood, appetite, sleep, and gut motility, with imbalances frequently linked to clinical conditions such as depression, anxiety, and digestive disorders. Fluctuations in hormonal status, particularly estrogen, can directly impact the synthesis and receptor sensitivity of serotonin.
