You may need further blood testing to see how your body is responding to the donor blood and to check if your blood counts have reached an appropriate level.
For example, if before the transfusion you were anemic, meaning you had low levels of red blood cells, your doctor will check to see how much the transfusion raised your red blood cell count.
Or, if you've had low platelets because of chemotherapy drugs, your doctor may test your blood to see whether the transfusion sufficiently boosted your platelet count. Some conditions require repeated blood transfusions.
