Frequently Asked Questions

How do I know if I am eligible for a clinical trial?
Clinical trial eligibility depends on specific inclusion and exclusion criteria set by researchers. Common factors include your age, diagnosis, disease stage, prior treatments, overall health, and sometimes genetic markers. Our eligibility checker asks about these factors to give you a personalised assessment of your likelihood of qualifying.
Can anyone participate in a clinical trial?
Not everyone qualifies for every trial. Each study has specific criteria to ensure participant safety and reliable results. However, there are thousands of trials recruiting in the UK at any time, and many people who want to participate can find a suitable study. Even healthy volunteers are needed for Phase 1 and bioequivalence studies.
What disqualifies you from a clinical trial?
Common exclusion criteria include certain comorbidities, pregnancy, organ dysfunction, recent participation in another trial, and specific prior treatments. However, each trial has different criteria — being excluded from one does not mean you cannot participate in others. Our checker identifies common red flags.
Does this eligibility checker guarantee I will be accepted?
No. This tool provides an indicative assessment based on common eligibility patterns across clinical trials. Final eligibility is always determined by the research team during screening, which may include blood tests, imaging, and a full review of your medical history. Think of this as a helpful pre-screening guide.
Is the eligibility checker free to use?
Yes, the TrialConnect Eligibility Checker is completely free. No registration is required, your answers are processed entirely in your browser, and no personal data is stored or shared with anyone.
What should I do if the checker says I'm likely eligible?
