💡 Screen failure in precision medicine trials is typically framed as a recruitment problem, but it’s more often a design problem.
Across Sano-supported rare disease programs, eligibility rates among participants who complete onboarding run as high as 98%. This means the funnel works. The fracture point comes after eligibility confirmation, when participants are asked to order a genetic testing kit.
Across studies, the proportion of eligible participants who actually order a kit ranges from 28% to 97%. That variance is enormous, and it is almost entirely shaped by how the testing pathway was designed.
At-home testing options, clear instructions, timely follow-up, genetic counseling access, and transparent communication about results all determine whether an eligible participant continues or drops out at exactly the moment they are asked to take a concrete step.
Sponsors who focus only on top-of-funnel volume miss this entirely. The real question is what happens to eligible participants after confirmation.
