The app gives you two options

The first option: Register as a new donor by filling in your personal information and you will be contacted when the blood is needed - if you suffer from chronic diseases or you are under the age of 18 years or older you do not have to register -
The second option: It is to search for a donor through the blood group and contact him. Please do not use this feature to annoy people registered in the application and use it in emergency cases. This feature is for hospital workers.
