Healthy volunteers wanted: your samples could unlock disease mysteries

NCT ID NCT00090662

First seen Jun 24, 2026 · Last updated Jul 29, 2026 · Updated 4 times

Summary

This study collects blood, urine, stool, and other samples from up to 150 healthy volunteers aged 18 to 85. Researchers will use these samples to compare with samples from patients who have too many eosinophils (a type of white blood cell), which can cause disease. The goal is to better understand these conditions, not to test a treatment. Volunteers are paid for their participation.
