Analysis of Peripheral Serotonin Levels in a Control Cohort

France100 participantsStarted 2025-06-23

Plain-language summary

The goal of this observational study is to measure serotonin levels in in a control cohort. The main question aims to determine the mean serum serotonin level in a cohort of adult controls, based on age and sex. This will allow for the establishment of reference values. We will also measure the different metabolites of tryptophan. These measurements will be performed on residual blood samples in the laboratory, after blood collection carried out as part of routine care. Thus, patients will not need to undergo an additional blood draw.
