Background: Blood is essential for human survival though it is a scarce and precious resource. Blood Transfusions also have some risks, like immunomodulation in the recipients, transmission of infectious agents, and may lead to serious adverse reaction. Hence, it is necessary to make an efficient use of blood and blood products.

Aims and Objectives: With this background, the present study was carried out at the blood bank of Medical College and Hospital, a tertiary care hospital of West Bengal, India to evaluate the utilization pattern of blood and blood components.

Materials and Methods: Facility based, observational, descriptive, and cross-sectional epidemiological study was conducted on the basis of secondary data collected from records of blood bank, medical college, Kolkata, regarding blood and blood component transfusion pattern of patients who were admitted in medical college and hospital and received blood and blood components from blood bank medical college, Kolkata during period from September 1, 2021, to September 15, 2021.

Results: Total number of transfusion recipients during the study period was 1339. Total 2621 no of blood and blood components were issued. About 66.84% (895) of all recipients were transfused with single unit of blood or blood component. Packed red blood cells were the maximum utilized blood component. The most common diagnosis for patients requiring blood and blood components was anemia.
