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

Determining Paediatric Usual Values for Hormones Dosages by Mass Spectrometry

Assistance Publique - Hôpitaux de Paris · NCT06694415

This project will try LC‑MS/MS hormone testing on blood samples from kids and young people (up to 20 years) to create normal reference values.

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.

Who should consider this trial

Good fit: Kids and young people aged 20 years or younger who are undergoing a routine blood draw, are clinically well without known or suspected endocrine disease, and have no acute infection or inflammatory disorder are ideal candidates.

Not a fit: Patients with known or suspected endocrine disorders, or those with acute infectious or inflammatory conditions, are excluded and will not benefit from this reference-value collection.

Why it matters

Potential benefit: If successful, clinicians will have more accurate and specific pediatric hormone reference ranges that can improve diagnosis and treatment decisions while reducing reliance on less-specific immunoassays.

How similar studies have performed: LC‑MS/MS is widely adopted and prior work has successfully produced adult and some pediatric reference data, though comprehensive multicenter pediatric norms remain limited.
