Healthy adults needed to help define 'Normal' immune levels for better infection diagnosis
NCT ID NCT07666191
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study will collect blood and nasal swab samples from 100 healthy adults aged 18 to 65 to establish normal reference values for immune markers called interferons. These markers can help doctors tell if a person has an active viral infection. By defining what is 'normal,' the study aims to improve diagnosis and monitoring of diseases like COVID-19 and flu.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- What this could lead to
- If successful, this study could provide reliable reference values for immune markers, helping doctors better diagnose and monitor viral infections.
- What could go wrong
- This is an observational study with only 100 healthy adults, so results may not apply to everyone. It does not test any treatment.
