Abstract
In the last decade a special focus has been based on blood donation system. This is due to two key factors: decline in the number of donors and rising amount of infectious diseases incidence, which increase cost of donated blood procurement. According to WHO recommendations, one of the factors that will improve viral safety of donated blood is information space which includes medical facilities and blood centers. We have analyzed information flows in Pavlodar Region Blood Center in order to formalize them for creation of an information system model.
