Am I able to give blood?

Check online if you're able to donate!

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.

1. Age

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 not allowed to give blood, then you may be able to donate plasma if you weigh at least 50 kg.

Want to donate plasma?

Want to donate platelets?

Are you transgender? Being transgender is not a reason to prevent you donating. A deferral period may apply for some transgender individuals. Read more at  

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

      If you are from a country where aids or hepatitis are common you will be eligible to donate blood 1 year after departing the risk area. 

      If you are from a country where malaria is common you will be eligible to donate blood and blood platelets no sooner than 3 years after departing the malaria risk area. In the meantime, you will be eligible to donate plasma after a deferral period of no more than 1 year. 

      If in the period between 1980 and 1996 you spent a total of more than sixth months in the United Kingdom (England, Scotland, Wales, Northern Ireland), the Isle of Man, Jersey or Guernsey, Gibraltar or the Falkland Islands, we are sorry to say that you are not eligible to donate.

      5.  Operations

      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 dental filling or the fixing of a crown: 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).

      7. Pregnancy

      You can't give blood, plasma or platelets during pregnancy or in the six months following the end of the pregnancy .

      8. Procedures involving needles for cosmetic or therapeutic purposes, e.g. piercings or tattoos

      If you have had a tattoo, (earlobe) piercing or permanent make-up applied, you must wait four months.  

      Have you had acupuncture/dry needling/myofascial therapy or other therapeutic treatment using needles?

      • If this was performed by a doctor, you do not have to wait and can donate immediately.
      • If this was not performed by a doctor, you may donate again if you can show a valid certificate or proof of certification. You can find a template certificate here (.pdf). Without a certificate/proof of certification, you must wait for a period of 4 months from your last session.

      9. Contact with a person's blood as a result of an accident involving a prick, cut, splash or bite

      If another person's blood (or a bodily fluid such as saliva, amniotic fluid, etc.) has been in contact with your broken skin or mucous membranes, you will have to wait four months before being eligible to donate again. You will also have to wait four months if you have been pricked by a needle or sharp object which may have had blood on it, or if you were bitten by another person.

      If, following this type of incidental contact, you received PEP (post-exposure prophylaxis) treatment to prevent HIV, this four-month deferral period continues to apply.  

      For example: you are a nurse and you accidentally pricked yourself with a needle which you had just used on a patient, or your eye was spattered with blood when assisting in an operation.

      10. Illnesses or infections

      Fever or illness caused by a viral or bacterial infection

      Wait for 14 days after you've fully recovered.

      Tick bite

      • 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 have had Lyme disease and/or Lyme disease symptoms, wait until four weeks after the symptoms have disappeared and the treatment has come to an end   

      In the case of other specific infections or diseases  

      • If you are HIV-positive or have AIDS: you may never donate, even if you are taking antivirals (ART: antiretroviral therapy) and have an undetectable viral load (see 12. Medication/vaccinations).

      • If you have ever had or tested positive for hepatitis B, C or syphilis: you must not give blood.
      • If you suffer from haemophilia (a blood coagulation disorder): you must not give blood. 

      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.

      The deferral periods remain valid if you take preventive medication to prevent HIV infection, referred to as PEP or PrEP (post-exposure or pre-exposure prophylaxis), see 12. Medication/vaccinations.


      You must not give blood or platelets for 28 days after sexual contact with a man diagnosed with ZIKA infection in the three months prior to sexual contact or with a woman diagnosed with ZIKA infection in the eight weeks prior to sexual contact. Donating plasma is allowed in these situations.

      12. Medication/vaccinations

      If you are taking medication or have just been vaccinated, this medication or vaccination does not usually present a problem when giving blood, plasma or platelets, but the underlying reason for the medication or vaccine might.
