Blood donation

Each year, the medical service organises blood donation campaigns in collaboration with HUG and/or EFS (typically twice a year). These campaigns have consistently represented a significant contribution of the Organization to the dwindling blood reserves in the region: take part in this act of solidarity which is essential for the benefit of all!

On this page you will find information on CERN's upcoming campaigns, information on what happens following a blood donation and the compatibility of different blood types.

Next campaign will be announced here in due time.

Blood barometer in Geneva

The blood barometer in Geneva, which is regularly updated, shows that blood supplies are currently running extremely low. We therefore hope to see many of you during this collection!
