Summary

This study aims to collect blood and sputum samples from 300 healthy adults aged 18-65 to create a comprehensive database of normal health markers. By analyzing genetics, proteins, and other molecules, researchers hope to better understand what 'healthy' looks like and improve early disease detection. Participants must have no chronic diseases or recent infections.
