Who these studies look for
“Healthy” is decided at screening, not by you. Sites usually check vital signs, blood and urine tests, an ECG, your medications and sometimes your BMI or smoking status. A study can still turn you away for reasons that have nothing to do with being unwell, such as timing or a full roster.
Matching a page like this one never means you qualify. Each research team decides eligibility at screening.
