- bank your own blood before surgery.
- do not bank your own blood before surgery.
key points to remember
- getting a disease from a blood transfusion is very rare in canada. the risk of infection from a blood transfusion is higher in less developed countries.
- if you have had many blood transfusions, your body may have formed antibodies against donated blood. your body mistakes the new blood as harmful and tries to destroy it. careful testing helps reduce the risk for these problems.
- there are risks from getting a blood transfusion, some related to errors with the labelling of the blood. the risk of these errors is the same whether you bank your own blood or receive donated blood.
- your body may not have time to replace the blood you banked before the surgery. this means that you may not be able to stand losing much more blood during surgery before you'd need a transfusion. in some cases, it's possible that you wouldn't have needed a transfusion at all if you had not banked blood before your surgery.
faqs
why might you bank your own blood?
if you are going to have surgery and expect to need a blood transfusion, you may want to bank your own blood a few weeks before the surgery. if you do need a transfusion, doctors can use your own blood.
many people consider this choice to protect themselves from the risks of disease or mismatched blood that are linked to blood transfusion.
how likely are you to have a reaction to a blood transfusion?
one risk of getting a blood transfusion is a transfusion reaction.
transfusion reactions occur when the blood you are given does not match your blood type. this matching error is rare. the lab may mislabel a unit of blood. a doctor, nurse, or technician may misread the label before the blood is given to you.
getting the wrong blood type happens rarely, up to 4 times for every 1 million units of blood transfused.footnote 1 a transfusion reaction may be mild or severe. a severe reaction can be life-threatening.footnote 2
it's possible to have a mild transfusion reaction even if your blood and the blood you are given are matched correctly.
some people, especially those who have had many blood transfusions, make antibodies against the blood they receive. their immune system mistakes the new blood as harmful and tries to destroy it. careful testing helps lower the risk for these problems.
the risk for an error in reading or labelling is the same whether you bank your own blood before surgery or receive a transfusion of donor blood. an error in reading or labelling may also mean that you receive the correct blood type during your surgery but not the blood you banked.
how likely are you to get a disease from a blood transfusion?
getting a viral infection, such as hepatitis or hiv, from a blood transfusion is very rare in canada. guidelines enforced by health canada's therapeutic products directorate (tpd) guard the collection, testing, storage, and use of blood. the risk of disease from a blood transfusion is higher in less developed countries.
it's possible for blood to become contaminated with bacteria during or after donation. getting a transfusion with blood that contains bacteria can lead to a bacterial infection that affects your whole body. you face the same risk for bacterial infection whether you bank your own blood before surgery or receive a blood transfusion of donor blood.
what are the risks of banking blood?
because blood can't be stored very long, you must bank your blood a few weeks before your surgery. this may not allow enough time for your body to make enough new blood to replace what you banked before surgery. you may have less blood than normal at the time of surgery, so your body may not be able to lose much more blood before needing a transfusion. in some cases, it's possible that you would not have needed a transfusion at all if you hadn't banked blood before surgery.
you may not be able to bank enough blood for your surgery. most people are able to safely bank 2 to 4 units of blood before surgery. if you are having major surgery that may require more blood than this, you may need more than you can safely bank.
talk with your surgeon about how much blood you might need for your surgery.

personal stories about banking blood before surgery
these stories are based on information gathered from health professionals and consumers. they may be helpful as you make important health decisions.
i am very concerned about the risk of getting hiv from a blood transfusion. i know the risk is very small, but even that small risk is too great for my comfort. i am banking my own blood before my surgery to reduce this risk even more.
frank, age 50
after talking with my doctor, i feel much better about the safety of blood transfusions. she pointed out that the main risk is from having a reaction to the blood, and the risk is about the same whether i bank my own blood or not. i'm not going to bank my blood before my surgery.
margaret, age 47
i had surgery a few years ago and had to have a blood transfusion. i had a pretty bad reaction to the transfusion, and my doctor tells me this is likely to happen again. it has something to do with an uncommon antibody in my blood that makes it react with most other blood. now i have to have surgery again, and my doctor says i can reduce the risk of having another transfusion reaction by banking my own blood ahead of time. but they also said that they will keep looking for blood that my antibodies won't react with. for now, banking and using my own blood seems safest to me.
ginger, age 60
i was considering banking my blood before my surgery. i asked my doctor how much blood i was likely to need during the surgery, and he said not very much. in fact, it is possible i will not need a transfusion at all. but he also said that if i chose to bank my blood before the surgery, i might become anemic and need a transfusion i could have avoided if i hadn't banked my blood in the first place. i've decided not to bank my blood before my surgery.
