1) To make sure the blood administered have altered the blood density as intended. 2) to be sure you are not losing it and need more.
The red blood cell counts will be more accurate as the blood plane at that time will have elevated and show up on a blood assessment determining that blood infusion effective. The blood test obtained after that one hour will show even more progress/effectiveness of the transfusion.
