What is my blood tested for?

Safety is paramount for Sanquin Blood Supply, for both donors and patients.
All of the donated blood is tested for 4 infectious diseases than can be transmitted via blood:

The blood of new donors is also tested for HTLV-I/II. The pathogens that cause these five diseases can remain present in blood for a long time, sometimes for life. If you have a virus or a bacteria in your blood, you carry the disease. You may not notice this at all, but your blood is contaminated.

If we discover you are carrying one of these five infectious diseases, we will always inform you.
