New blood tests could help monitor Flare-Ups in kids with arthritis
NCT ID NCT07356804
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study measured two newer blood markers (calprotectin and serum amyloid protein) alongside standard tests in 20 children with juvenile arthritis and related conditions. The goal was to see if these markers could better track disease flare-ups in everyday clinic visits. The study did not test any treatment, only observed changes over time.
