Am I able to give blood?
Safety is our number-one priority
We want donation to be safe both for you as a donor and for the patient(s) who will be receiving your blood. As such, in some cases it may be that you won't be able to donate blood, plasma or platelets either for a temporary period or permanently. To determine who can give blood, before you donate we'll ask you a number of questions and perform a brief examination. All our selection criteria are based on scientific evidence.
When are you allowed/not allowed to give blood?
To ensure that the blood we supply is safe, we apply scientifically based selection criteria. Want to know more? Then simply contact the doctor at your donor centre.
You must be between 18 and 66 to be a donor. If you have given blood, plasma or platelets before, you can continue to do so. But at 66 years of age it should be no more than 3 years since your last donation, and you will need permission from the doctor at the donor centre.
2. Weight, height and sex
Your ability to give blood will depend on your weight, height and sex. You can check your eligibility to give blood online.
Are you no longer allowed to give blood, then you may be able to donate plasma or platelets if you weigh at least 50 kg.
3. Intervals between giving blood, plasma and platelets
You can give blood up to four times a year. Each time you need to wait at least two months before doing so again.
However, you can give plasma and blood platelets every two weeks.
If you want to give blood, plasma and/or blood platelets at the same time, you'll need to wait until two weeks after giving blood to give plasma or platelets again and at least two months to give blood again.
4. Travelling abroad
Have you had any endoscopic surgery or investigations?
If so, you need to wait for two to four months before you can give blood, plasma or platelets again. The waiting period depends on how the doctor carried out the investigation:
- with a rigid scope: two months;
- with a flexible scope: four months.
Have you had a standard operation?
After a standard operation you also need to wait for a little while before giving blood, plasma or platelets:
- minor surgery: two months;
- major surgery: four months;
- gastric bypass operation: once you've had such an operation, you'll only be able to give plasma.
Have you had a transfusion?
After a transfusion you'll need to wait for four months before giving blood, plasma or platelets.
6. Dental visits
Depending on what the dentist did, you may need to wait for a little while before reporting as a donor:
- a filling: one day;
- tartar or root-canal treatment or tooth extraction: seven days;
- routine check-up: no waiting period (i.e. there is no need to wait before giving blood, plasma or platelets).
You mustn't give blood, plasma or platelets during pregnancy or in the six months following childbirth.
8. Procedures involving needles for cosmetic or therapeutic purposes, e.g. piercings or tattoos
You must wait for a period of four months after having your ears pierced, a body piercing, a tattoo, permanent make-up, acupuncture or myofascial release therapy (dry needling). However, if an accredited acupuncturist or a doctor performed the acupuncture, you don't need to wait and can give blood, plasma or platelets straight away, but in this case please bring evidence of their accreditation.
9. Contact with a person's blood as a result of an accident involving a prick, cut, splash or bite
If you've had contact with anyone's blood, you'll need to wait for four months before reporting as a donor again (e.g. as a nurse, you pricked yourself with a needle you had just used on a patient; cuts, splashes and bites may also lead to contact with someone's blood).
10. Illnesses or infections
Fever or illness caused by a viral or bacterial infection
Wait for 14 days after you've fully recovered.
- If the tick was removed within 24 hours, there is no waiting period.
- If the tick was NOT removed within 24 hours and you don't experience any symptoms: wait until one month after the tick bite.
- If you experience symptoms and/or Lyme disease: wait for 14 days after the symptoms disappear and the treatment comes to an end.
Other specific infections or illnesses
You mustn't give blood:
- if you're HIV-positive;
- if you suffer from haemophilia (blood-coagulation disorder).
Patients with haemochromatosis
People with a hereditary form of haemochromatosis but who are otherwise healthy may donate blood, plasma or blood platelets) provided they produce an annual certificate from their doctor confirming that:
- they are in the maintenance phase of treatment and their serum ferritin is within the reference levels;
- they need a phlebotomy no more than once every two months;
- their organs are undamaged by their haemochromatosis.
Are you a haemochromatosis sufferer who meets the criteria above and would like to give blood, plasma or platelets?
- Start by completing the donor self-assessment test.
- Download the medical certificate and accompanying letter for your doctor.
- Ask your doctor to complete and sign the certificate.
- Bring the certificate and the results of a recent (no more than a month old) serum ferritin lab test to the blood collection for the blood collection doctor.
Good to know:
- The certificate must be renewed each year after giving blood for the first time.
- As a haemochromatosis patient, you can give blood up to six times a year, with at least 60 days between each blood donation.
- As a hemochromatosis patient you can also donate plasma or platelets. Keep in mind that after a plasma or platelet donation you have to wait 14 days before you can donate blood again.
