Background : Blood is a resusciate source of life which there is no replacement for it. Limited time of preserving, screening tests of blood health, group determining, and cross-matching, that necessitate personal and laboratory costs, increase the importance of correct request and suitable consumption. This study was conducted to determine the frequency of blood transfusion and its components and calculate the ratio of C/T. Materials and Methods: This descriptive-analytic study included 648 patients for whom blood and blood components were requested during the study. The data regarding the variables were recorded in a checklist and then were analyzed using the SPSS software. Results: The results showed that during the study 7746 patients were hospitalized and blood or blood components were requested for 648 (8%) of them. Out of these patients, 265 (40.9%) received transfusions of blood or its components. Packed cell was the most frequently transfused component (71.3%). The mean HB (hemoglobin) in the patients before transfusion was 9.49 gr/dl. Chronic anemia was the most prevalent indication of transfusion, and femoral fracture surgery was the most frequent operation needing blood transfusion. The C/T ratio was found to be 1.1. Conclusion: In this study, 59.1 % of the requested units were not used. Realizing requests based on scientific needs, and costs of production, preserving, separating components, transporting them to hospitals, and cross-matching including laboratory needs and manpower are recommended.
