UDN guide to diagnosing medical mysteries published


Since accepting its first patient in 2015, the Undiagnosed Diseases Network (UDN) has been working towards creating a model system for diagnosing medical mysteries. The network's goals? Accelerate the diagnosis of rare or previously unrecognized diseases; improve clinical management of these disorders; and advance research.

Building the UDN has already brought insights how to best diagnose hard to define medical cases. This type of work requires doctors to gather data, collaborate and cross disciplines in ways that are unprecedented.

UDN members have now published a how-to guide for diagnosing medical mysteries for medical centers nationwide outline the framework for how this can be successful.
