ABCs of eligibility for donating blood, platelets and plasma

Acupuncture performed with single-use, disposable needles does not affect your ability to donate. If you are not sure what type of needles were used during your treatment, you must wait three (3) months before you are eligible to donate.

The minimum age to donate is 17. There is no upper age limit for donating in Canada.

If you are between 17 and 23 years old and have never donated before, you must meet our minimum height and weight requirement as outlined in the table here. If you are below 147 cm (4’ 10”), you may become eligible when you turn 23.

There is no upper age limit to donate blood.

First time donors aged 67 and older are not eligible to donate platelets and/or plasma on their first donation. There is no upper age limit for repeat donors.

At a dedicated plasma donor centre, first time donors must be under age 71. There is no upper age limit for repeat donors.

If you are a first-time donor, please call us at 1 888 2 DONATE (1 888 236-6283) to discuss your eligibility.

Donors must not be impaired at the time of donation as this prevents us from obtaining informed consent.

If you have allergies, you are eligible to donate if you are feeling well at the time of your appointment.  Please remember to bring a list of your prescription and non-prescription medications with you to your appointment.  

If you are allergic to skin cleaning solution, adhesive medical tape or other medical supplies, please inform our clinic staff (alternatives are available for donor comfort and safety). Our team members want to ensure your experience is as comfortable as possible. 

If you experience an allergic reaction or are feeling unwell as a result of donation, please alert donor centre staff, visit our donor health and safety page, and/or call to speak with one of our trained health professionals at 1 888 2 DONATE (1 888 236-6283). 

Anemia is a term used to describe a low level of hemoglobin (or healthy red blood cells).

There are many causes of anemia. These may include iron deficiency, vitamin B12 deficiency, altered function of vital organs, various types of cancers, etc.

As blood donation leads to removal of red cells, it can worsen anemia. As such, people with anemia, as well as those who do not meet the hemoglobin thresholds, are not able to donate.

Every donation is tested for certain infections that may be transmitted by blood, to ensure the safety of Canada’s blood supply. These tests are extremely accurate at detecting the presence of infections, called “true positives”. However, sometimes these tests detect an infection even when it is not present, called a “false positive” result. 

When we have a donation where our first set of tests detect an infection, we do additional testing to confirm these results. This helps us determine whether the tests were a true or a false positive. 

Canadian Blood Services has a re-entry program for some false positive results to allow otherwise eligible donors to be re-tested after a six (6) month waiting period. 

If you have received a false positive result in the past and would like to know if you can be re-tested, please call 1 888 2 DONATE (1 888 236-6283) to speak with one of our trained health professionals.

First time donors aged 17 to 23 must meet these height and weight criteria

Why do you need to know my gender before I donate?

Canadian Blood Services values all blood donors and understands that selecting either male or female may not align with how some individuals identify. Unfortunately, due to limitations of the binary registration computer software system we use, all donors still need to register as either male or female.

We know this isn’t ideal, and we understand there is a distinct difference between biological sex and gender. We are actively working on changes to our processes in consultation with trans and non-binary community members, as well as the registration software owner, to make our registration and screening practices more inclusive.

Hereditary hemochromatosis is a common genetic disorder causing the body to store too much iron. If you’re looking for more information about hemochromatosis, click here.    

Individuals with hemochromatosis are eligible to donate blood provided they meet all other Canadian Blood Services donation criteria.  

For those who are donating blood and also having blood removed (phlebotomy) at a medical facility, there must be a minimum of seven (7) days between the two procedures.

Hemoglobin is an iron-rich protein in red blood cells that carries oxygen throughout the body. Blood donation, which removes red blood cells, also removes hemoglobin. As a result, frequent blood donors can develop low hemoglobin levels or anemia. 

To ensure donors have sufficient hemoglobin levels after donation a minimum hemoglobin level is required before each donation. Hemoglobin level is tested using a fingerpick test.  

For whole blood, donors registered as male must have a hemoglobin level of at least 130 g/L and donors registered as females must have a hemoglobin level of at least 125 g/L. 

For plasma and platelet donations, the hemoglobin level must be at least 125 g/L for both males and females.

Hepatitis is an inflammation of the liver caused by an infection or a non-infectious condition such as a side effect of medication.  

Donors with a history of viral hepatitis may be eligible to donate six (6) months after full recovery unless the cause is known to be from hepatitis B or C virus. 

If you have ever tested positive for hepatitis B or hepatitis C, you are not eligible to donate, even if you have never had symptoms. 

If you had hepatitis in the past and don’t know the cause, you may be eligible to donate if you have been fully recovered for more than six (6) months.  

If you live with or have had sexual contact with a person who has or had hepatitis, call us to speak with one of our trained professionals at 1 888 2 DONATE (1 888 236-6283) to discuss your eligibility. 

Those living with HIV or who have tested positive for HIV are not eligible to donate. 

People who have had sexual contact with a person who has tested positive for HIV are not eligible to donate for 12 months since the last sexual contact. 

• People who take oral pre-exposure prophylaxis (PrEP) or post-exposure prophylaxis (PEP), must wait four (4) months since last use to donate, as low levels of HIV may be missed in testing. PrEP and PEP medications can interfere with the HIV testing which we rely on as part of our multi-layered approach to safety. HIV care has reached a point where people’s viral loads can be undetectable, however undetectable equals untransmissible (U=U) only applies to sexual transmission of HIV. Unfortunately, even those who have an undetectable viral load may transmit the virus through blood transfusion. The chance of transmission is much higher with a bag of blood or blood component (plasma, platelets) due to a much higher total amount of virus that the recipient is exposed to. 

For additional information, please call to speak with one of our trained health professionals at 1 888 2 DONATE (1 888 236-6283). 

If you are taking hormone medication and are otherwise eligible, you can donate. 

Those who have a history of intravenous drug use (injecting into a vein) are not eligible to donate because of the possibility of transmitting an infection. 

When people donate blood, their body’s iron levels also decrease which may cause anemia. People with anemia, as well as those who do not meet the hemoglobin thresholds, are not able to donate. 

Iron deficiency is common. Those who donate regularly or have heavier menstrual blood losses, recent pregnancy, or a meat-free diet are most likely to develop iron deficiency. 

One laboratory test used to determine iron levels is called ferritin. A low ferritin result is a reliable indicator of iron deficiency.

If you have been diagnosed with cutaneous or discoid lupus (limited to skin) you are eligible to donate.

If you have been diagnosed with systemic lupus erythematosus you are not eligible to donate.

If you have had malaria in the past, you may be able to donate source plasma if it has been six months or more since your recovery.  

If you have recently travelled to a region where preventative medications are recommended for malaria and the chances of exposure are high, you may need to wait before donating, depending on your length of stay in certain regions. This is because the chance of having a new or previously unrecognized malaria infection diminishes over time  

Review the travel section of this page for more information about waiting periods to donate. 

People with a history of malaria are not eligible to donate whole blood or platelets, or plasma for transfusions. This is because the parasites that cause malaria can lie dormant for decades. No matter how much time has passed since someone has recovered from malaria, there remains a small chance they could still carry malaria parasites in their blood. 

The criteria for source plasma donation are different, because the process used to manufacture medications from plasma removes the parasite that causes malaria.  

There is currently no Health Canada-approved test available that can screen blood donors for an active malaria infection. However, Canadian Blood Services is actively collaborating with an international malaria test developer to evaluate and implement a nucleic acid test (NAT) for malaria as an enhanced blood safety measure within our donor screening process.

Learn more about malaria and blood donation and our ongoing work to review and implement alternative approaches to the existing donor screening process for malaria.  

To learn more about waiting periods associated with travel to malaria-endemic regions, review the travel section of this page or call us at 1 888 2 DONATE (1 888 236-6283).

Most medications do not prevent you from donating, however some medications may impact eligibility because: 

• they may help manage health conditions that can change eligibility, or; 
• when present, even in small quantities, in the donated blood or blood product can be harmful to the recipient, or;  
• they may make certain parts of the blood not useable for transfusion.  

If you are currently taking medication, please review our list of common acceptable medications. If your medication is not listed, or you have additional questions about eligibility, please call to speak with one of our trained health professionals at 1 888 2 DONATE (1 888 236-6283).

Ulcerative colitis is a condition where inflammation in the colon can cause bacteria to enter a person’s bloodstream, even if they are feeling completely well. 

Donors are eligible to donate once they are symptom free and off medication for five (5) years. 

Most vaccinations do not prevent you from donating, however there are a few that require a short waiting period. Review our full list of vaccinations below to check your eligibility. 

If you received a vaccine that is not listed above, please call to speak with one of our trained health professionals at 1 888 2 DONATE (1 888 236-6283).  

To donate blood, platelets or plasma, you must weigh at least 50 kg (110 lbs.). If you are between the ages of 17 and 23, and have never donated before, you must meet our weight and height criteria shown in the table below.

Although there are no upper weight limits for eligibility to donate, our donation beds do have weight restrictions as per their manufacturers to ensure no harm or discomfort to the donor.

The donation beds in mobile donation settings can safely accommodate maximum weights of 350 lbs. or 500 lbs., depending on the location. Beds in our permanent donor centres can safely accommodate up to a maximum weight of 300 lbs. or 400 lbs., depending on the location. At select facilities we do have donation beds that can accommodate a maximum weight of 600 lbs.

We do our best to ensure our donor centres and mobile events are as accessible as possible, but it is always a good idea to phone us at 1 888 2 DONATE (1 888 236-6283) prior to your appointment, so that we can ensure you do not encounter any unexpected barriers to donation.

To donate plasma you need to be at least 50 kg (110 lbs.) and 145 cm (4’10’’).

If you are a first-time donor or to confirm your eligibility to donate plasma, please call us at 1 888 2 DONATE (1 888 236-6283). 

Why do you need to know my gender before I donate?

Canadian Blood Services values all blood donors and understands that selecting either male or female may not align with how some individuals identify. Unfortunately, due to limitations of the binary registration computer software system we use, all donors still need to register as either male or female. 

We require this information for donor and recipient safety reasons. For example, hemoglobin levels required, the volume of donations we can safety collect, and inter-donation frequencies differ, depending on whether a donor registers as male or female. We are actively looking at non-gendered ways to do this while ensuring safety for the donor. 

We know this isn’t ideal, and we understand there is a distinct difference between biological sex and gender. We are actively working on changes to our processes in consultation with trans and non-binary community members, as well as the registration software owner, to make our registration and screening practices more inclusive.
