NCT ID NCT00001406
First seen Sep 30, 2025 · Last updated May 14, 2026 · Updated 28 times
Summary
This study looks at why certain white blood cells (eosinophils) become overactive in people with allergies, parasitic infections, or rare immune conditions. Researchers will observe up to 800 participants aged 1 to 100, using blood tests, bone marrow samples, and other exams—but no experimental treatments are offered. The goal is to better understand these conditions, not to test a new therapy.
