Every time you give blood, you receive a Post Donation Donor card, which contains your personal details and our contact information. This card will make it easier for you to contact us, if you need to, after giving blood. You may, for example, experience a medical problem after donating, or be unsure about the suitability of your blood. By disclosing this information to us, you make it easier for us to assist you and you help ensure the safety of our blood stocks.

Please find a list of the most frequently asked questions below.
Can I choose who receives my donation?
No, donation of blood, plasma or platelets is and will always remain anonymous. The donation number associated with each blood bag will identify the donor, but the blood bag itself never indicates the origin of its contents. We never reveal donors’ names to recipients so it is not possible for you to choose who receives your blood, plasma or platelets.
Can I carry on as normal immediately after making a donation?
Yes, you can resume most activities after donating blood, plasma or platelets. However, during the first few hours after making a donation we advise donors to avoid extreme exertion since immediately after collection the blood’s ability to carry oxygen around the body is lower than normal.
We also advise against any hazardous work, very strenuous activity or sport for at least 12 hours after making a donation since your blood pressure may be lower or less stable than normal.
It’s also best to avoid standing up for long periods during the first four hours after making a donation to prevent dizziness, a drop in blood pressure or loss of consciousness.
What should I do if I suffer pain or irritation after making a donation?
The donation of blood, plasma or blood platelets does not normally cause complications. But some people may experience a reaction. Our staff at the blood collection points do all they can to manage these adverse donor reactions. Obviously, as a donor, your insurance will cover any additional medical expenses.
Consult your general practitioner if your arm hurts when you get home after giving blood, plasma or platelets. Or if you feel irritable, or generally unwell. Also inform us via www.rodekruis.be/postdonation or via the telephone number that you find on your post donation donor card.
What if I get ill or get a fever after my donation?
Do you get ill after your donation, or do you get a fever (> 37.5 ° C the first 72 hours after your donation)? Then you may have an infection that could already be present prior to your donation. After your donation you may also learn you were already ill at the time of your donation. Or you may take a positive COVID test in the 14 days after your donation. In all these cases, it is important that you notify us as soon as possible. In this way you help to ensure a safe blood supply.
Where can I obtain information about my blood values?
Contact our medical secretariat.
What tests does the Red Cross run on donated blood, plasma and platelets?
After collection, all donations are sent to the laboratory for screening. We run laboratory tests for hepatitis B and C, HIV and syphilis. All donations are then categorized by blood group, and we count the various types of blood cells and calculate the hemoglobin levels.
Will the Red Cross inform me of the test results?
We will not normally contact you if the results of all the laboratory tests are satisfactory. However, if our tests produce abnormal results which may have implications for your health, then your donor center will contact you in writing. In the letter, we will inform you of the test results so that you can consult a doctor. If our tests reveal a recent hepatitis B or syphilis infection in a donor, we are required by law to notify the authorities anonymously.
We will never disclose test results to anyone without your consent, even to the doctor treating you. In a few exceptional cases, the doctor at the donor center will invite you to come and discuss your test results in person.
What should I do if, after making a donation, I have doubts about whether it is safe to use?
It is important that you keep us informed at all times of any potential contamination risks. This is due to the so-called ‘window period’ – the period between first infection with a virus and the point at which the virus can be detected in the blood. During the window period – which can last from a few weeks to up to six months – the virus is undetectable, even via laboratory tests. As such, if you have only recently been infected, it is possible that the virus will not show up in your donation.
To avoid bringing contaminated blood into circulation, it is therefore crucial to let us know if you have any doubt whatsoever as to whether your donation is safe to use. You can either give us a call or use the Post Donation Donor card you were given when registering for the blood drive. The card gives instructions on what to do, a telephone number and some information about your donation.
What should I do with my Post Donation Donor card
Every time you donate you will be given a card with your personal details and a telephone number in case you later remember something after making a donation which you forgot to tell the doctor or in the event that you become ill within a week of making your donation. This information is extremely important so we have made it as easy as possible for you to let us know. On the back of the card you will find a freephone number to call, while your donation number which you will need to leave on our answer machine is on the front. Since every donor’s donation number is unique, you can dispose of the card after eight days.
What happens if there is a problem with my donation?
If our laboratory tests reveal abnormalities which make your donation unsuitable for patients, then it will be destroyed. Donations containing viruses which may contaminate a recipient’s blood will always be destroyed – for example blood containing hepatitis B or C, HIV or syphilis. We will also inform donors of any abnormal results found in their donations. We are also obliged to exclude any donors whose donation tests prove abnormal from giving donations in the future.
Blood products which are not suitable for transfusion can sometimes be extremely useful for other purposes, such as scientific and epidemiological research (always anonymous). The same applies to surplus quantities from each donation.
