Undiagnosed Disease Program
The Undiagnosed Disease Program (UDP) at CHOP offers personalized care for families who are struggling to pinpoint the cause of their child’s symptoms. The UDP harnesses the knowledge of clinical and research experts from across CHOP plus the power of comprehensive genetic analysis and other advanced diagnostic tools to improve diagnosis and treatment of undiagnosed diseases.
If your child is still undiagnosed after seeing multiple experts and you have a long list of inconclusive or negative test results, we can help. The UDP was built to provide families the medical guidance they need after they’ve exhausted other diagnostic options.
Our multidisciplinary team will review your child’s past test results and utilize specialized diagnostic tools to help understand your child’s condition. We’ll then connect your family with a clinical expert who will be able to map the best path forward for management and treatment.
Before contacting the UDP, review our checklist to make sure you’ve already taken all the necessary steps.
