No diagnosis
YOU DON’T HAVE A DIAGNOSIS?
Even if your illness (or your child’s) does not have a name or the diagnosis is not yet certain, you can contact our iRARE Centre.
We can explore with you if there are some possible avenues that can be taken to obtain a diagnosis in the health system or through research. It is also possible to register in some international registries where people share their information in the hope of finding someone with a similar disease or a researcher who might be interested in it.
