Before the blood test, the patient must not eat or drink for four hours.The patient should eat and drink normally before the urine test.The technician handling the urine sample should be informed of any medications the patient is taking.
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.
Yes, but only if the patient has B, or AB blood. Anyone can receive o blood.
This test requires a blood sample. The patient should have nothing to eat or drink (fasting ) from midnight the night before the test. Because lactic acid is produced by exertion, the patient should rest for at least one hour before the test.
Don't have sex or work out.
Yes. Failure to do so can result in death
Yes as the loss of blood can effect this disorder. Also it can effect the body giving to patient anemia they didnt have before.
Blood tests may be performed before the procedure to check for clotting problems and blood type, in case a transfusion becomes necessary.

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.
A blood transfusion - is giving a patient a quantity of blood to replace any that's been lost though an accident or injury. A small sample of the patient's blood is analysed to determine the blood group & type. This is 'cross-matched' with blood of the same type stored at the hospital. A unit (or 'bag') of blood is hung above the patient from a metal stand, and a needle leading from the bag is inserted into a vein in the patient. A combination of gravity, and the patient's heartbeat drains the blood from the bag into the body. The bag is replaced when empty or the donation is stopped once the patient's blood pressure returns to normal.
