L-ICP4Rare-DX
Improving the diagnosis and care for children affected by a rare disease
The ICP4RareDx project aims to improve the diagnosis of people living with a rare disease who have not yet received a confirmed diagnosis. Many patients, particularly children, face a long and complex “diagnostic odyssey”, often consulting multiple healthcare professionals over several years before receiving the correct diagnosis or, in some cases, remaining undiagnosed.
By working closely with patients, caregivers, and healthcare professionals, the project seeks to better understand the challenges people face throughout the diagnostic journey. These insights will be used to develop a coordinated diagnostic pathway that will form the basis of an Undiagnosed Disease Program in Luxembourg. The goal is to help people with suspected rare diseases receive an accurate diagnosis more quickly, improve coordination of care, and provide earlier access to the most appropriate treatment and support.
