Normal hormone levels in children measured by LC‑MS/MS

Is this trial a fit for you?

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This is a prospective, multicenter, non-randomized observational project using children and young people considered healthy to establish reference hormone values by LC‑MS/MS. An extra small blood tube (within safe volume limits) will be collected during routine clinic blood draws at participating AP‑HP pediatric endocrinology centers. Samples will be pseudonymized and entered into a secure REDCap database, and mass spectrometry analyses will be performed within the AP‑HP network under expert supervision. The resulting data will be used to produce pediatric reference ranges to support clinical interpretation when switching from immunoassays to LC‑MS/MS.
