A database query processing system for blood donation tracking includes a database, a network interface circuit and a processing circuit. The database stores records for a plurality of blood donors, each record comprising an amount of a blood component the blood donor has donated. The processing circuit determines an amount of a blood component a first donor may donate based on records for a plurality of donations made by the first blood donor and based on a limit of an amount of blood component the donor may donate in a predetermined period of time. The processing circuit further receives a request for the amount of the blood component the first donor may donate and transmits the amount of the blood component the first donor may donate to the remote computing device.
