People are rarely infected with HIV through blood transfusion now. Scientists have not always known what HIV was or how to detect it. During this time, many people were infected with HIV as a result of blood transfusion. Thankfully, now every blood sample collected is tested for a variety of diseases, including HIV.
The following tests are performed before the blood transfusion. 1. Hepatitus B 2. Hepatitus C 3. HIV 4. Treponima pallaidum (Symphillus) 5. Malarial Parasite 6. Creutz feldt Jacob disease or Mad cow disease

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.) Student Doctor

the transfusion reaction doesn't occur the first time an Rh+ patient is exposed to Rh- blood because the Rh+ patients body hasn't created the antibodies needed to attack the Rh- blood that it comes in contact with. the second time the Rh+ patients body comes in contact with Rh- blood, it will have the antibodies necessary to fight against Rh- blood.
Time. But you could also do dialysis or blood transfusion.

PABD is generally indicated when there is a reasonable chance that a blood transfusion will become necessary, when the patient is in adequate health to donate blood, and when there is sufficient preoperative time for the patient to donate.
Jehovah's Witnesses who have lost blood are entitled to refuse a blood transfusion even if it will inevitably lead to their death; but they have no right to sentence their children to die. A qualified doctor is entitled to give a blood transfusion provided the child's consent is given. If the doctor is unhappy about this (though why should any doctor be unwilling top save a child's life?), the case should be referred to a doctor who is free from such qualms. If the Jehovah's Witness parent seeks to intervene to prevent the transfusion, the case should be rushed to court, if there is time. If not, the child should be given blood immediately.
The most common time to find out is either when donating blood, or recieving a blood transfusion, or having surgery. If you don't know what type of blood you have, it is difficult to know what kind you would need in the event of a surgery.
Most of the time whole blood is not used because the patient's medical condition can be treated with a blood component and too much whole blood can raise a recipient's blood pressure. High blood pressure can have medical side effects
