Last time I gave blood, they take 470mls of blood, plus four test tubes partially filled as samples for testing. Some tests would be to check I don't have any disease, others for lab tests I suppose.
The answer depends on the clinical situation. In examples of extreme trauma, there are many documented cases where hundreds of blood components have been transfused during the course of treatment until the bleeding is finally controlled. In these cases, clotting factors must be monitored to prevent dilutional coagulation deficiencies and patient temperature maintained following the infusion of large volumes of cold blood products.
In non-hemorrhaging patients, the volume of transfused produced must be monitored to prevent non-cardiogenic pulmonary edema. When total transfused products approach one total blood volume, then the term "massive transfusion" is used.
I have found different units have different amounts. Usually less than 300 mL is the standard. Last week I gave two units-one of which had 252 mL and the other had 267 mL.

transfusion is required for you. Or you will die.
Blood infusion is a misused term for blood transfusion. This is where a person receives blood through an IV.
Blood transfusion does not affect personality.
People will receive a blood transfusion when there is a significant loss of blood, severe anemia, or as otherwise directed by a physician. On average, a transfusion of one pint of blood will raise hemoglobin levels by one gram. Hemoglobin is measured by grams per deciliter (100 milliliters) of whole blood.
Heparin is given after a transfusion to prevent blood clotting.

There are several different labels for the department, here are a few: Blood Bank, Blood Transfusion Services, Transfusion Medicine
If you receive a blood transfusion, you are under no obligation to "return" (or "donate") any blood to back the blood bank. This is true both before and after receiving a blood transfusion - i.e you do not have to have donated blood previously, before you can have a transfusion. (At least, this is how it works in the UK). Nice to know, really.
