Not generally. The point of a transfusion is to replace lost blood, so removing blood as you put it in from the transfusion defeats the purpose.
Sometimes before surgery, you will undergo "saving" blood, that is before surgery some of your blood is drawn and saved, so it can be put back in after surgery. (This is done weeks in advance, so your body has time to get its blood levels back to normal.)

After an operation, many patients need a blood transfusion.
Transfusion of your own blood (autologous) is the safest method but requires advance planning and not all patients are eligible.
transfusion is required for you. Or you will die.
Blood type A can receive a transfusion from blood types A and AB.
No, blood cannot be drawn during a transfusion as the purpose of a transfusion is to provide blood to the patient, not to remove blood from them. Drawing blood during a transfusion would disrupt the process and potentially cause harm to the patient.

It is very rare for you to have a blood transfusion. In most cases, you do not need one.
Diphenhydramine is generally ordered for patients before infusion of blood components if the patient has a history of mild/moderate allergic (urticarial) reactions during/following transfusion.
Pretransfusion blood typing and antibody screening of the patient's blood, followed by a complete crossmatch with type compatable donor blood products will prevent acute transfusion reactions.
Stop the transfusion immediately, monitor vital signs, and notify the healthcare provider. Chills and rigors during a blood transfusion could indicate a transfusion reaction which needs to be addressed promptly to prevent further complications.
Most patients will not require transfusion of blood components if 500 ML of whole blood is lost. However, depending on the patients underlying medical condition and cardiovascular/respiratory reserve, even small amounts of blood loss may lead to significant reactions requiring replacement.
