By donating your cells, you actively support the development of new therapies for cancer and other serious illnesses.
Across the globe, research institutions, universities, and pharmaceutical companies are working to develop innovative cell and immunotherapies — treatments that offer new hope, especially for people who no longer respond to conventional therapies.

Cell Donation. Everything you need to know – procedure, types of donation & your safety
Here you’ll find all the key information about the different types of cell donation, how the process works, and how we make sure your health is always protected.
From your first appointment to aftercare – we’re by your side: professionally, transparently, and personally.
Preliminary medical check – Your health comes first
Before most donations, a short medical check-up is required. It usually takes 20–30 minutes and includes:
- A personal consultation with a doctor
- A small blood sample
The exact process may vary depending on the type of donation. You’ll receive full details when we book your appointment.
