A blood transfusion is typically given when a person's blood levels are low and they need additional blood to help their body function properly. This can be due to conditions such as severe bleeding, anemia, or certain medical procedures. The decision to give a blood transfusion is made by healthcare professionals based on the individual's specific medical needs.
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

Time. But you could also do dialysis or blood transfusion.
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.
because both rh positive ann rh negative the anti boby is less
There is a risk of a transfusion reaction when a person with Rh- blood receives Rh+ blood for the first time. The reaction can range from mild to severe, depending on the individual's immune response. Prompt medical attention is necessary if a reaction occurs.
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.
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.
