The blood transfusion will start slowly so healthcare providers can watch for signs of a reaction. Even a small amount of donor blood can cause a reaction.

Tell them if you have signs of a reaction, such as pain, nausea, or itching.
It is always important to reassess bleeding and take a platelet count after a transfusion. The normal platelet count is between 150,000 and 400,000 per cubic millimeter. The American Cancer Society explains that the risk of dangerous bleeding becomes elevated when the count drops below 20,000 per cubic millimeter.
