Summary
This completed study measured normal tryptase levels in 402 children aged 0-18 to help doctors better diagnose mast cell disorders like mastocytosis and MCAS. Researchers used leftover blood from routine tests in children undergoing surgery. Knowing these normal ranges could reduce years of misdiagnosis and improve care for affected children.
