All blood donors in Denmark must be able to speak and understand Danish. Before donating blood you go through a written and oral interview in Danish, and it is important that you understand all the questions and are able to answer them correctly. These regulations are made to prevent misunderstandings between the donor and the staff of the blood bank.
You must have a Danish social security number in order to become a blood donor.
In general everybody who is physically well, between the ages of 17 and 65, and weigh more than 50 kilos are welcomed as blood donors.
