You may not donate blood if you received a blood transfusion in or after 1980, in other words you have received blood from another person. This does not apply if you only received a transfusion of your own blood.
Adjustment of policy in autumn 2024 Sanquin is adjusting their policy on safe blood donation after having received a blood transfusion. We will announce more about this in the last quarter of 2024. The reason for the prior transfusion (illness, accident, chronic condition, etc.) will be decisive in determining whether or not you can become a donor.
