Depends: This depends on what your starting blood counts are, what your underlying medical comorbidities(ailments) are, and how your body is responding to blood loss. For some people, it may be many mLs, for others, particularly if they've had ongoing blood loss prior to the surgery, it may be after only a small amount(as in less than 200 mLs).

A 37-year-old female asked:
Do I have a choice of whether I wish to receive a blood transfusion before a surgery if things were to go wrong and I lose lots of blood during????

Yes: You are free to refuse blood transfusions if you want. In this situation, your will pay for your bad decision with your life. Jehovah's Witnesses do this stuff. They die. Most surgeons would refuse to operate until you wise up. Blood component therapy has risks but today they are nothing compared to the risks of believing international scare stories and refusing needed health care.
