Biosamples are human biological samples such as blood, urine, saliva, or tissue collected during regular medical care, clinical trials, or research studies.

These samples contain important biological information, including cells, proteins, DNA, and RNA. Studying them helps researchers better understand diseases and how they affect the body.

For people living with rare diseases, biosamples play an important role in helping researchers better understand how diseases develop and progress. Every sample may provide insight, and every insight brings researchers closer to better care.

We understand it’s important to know where your sample is and how it’s used. Here’s an overview of what happens if you choose to donate.

Before donating a biosample, you’ll receive clear information about what participation involves, including how your sample may be used, stored, and protected.

Agreeing to donate is entirely voluntary and confirmed through an informed consent process. This ensures your rights, preferences, and choices are respected at every stage.
