BACKGROUND:Adolescence is the formative period of life when the maximum amount of physical, psychological and behavioral changes takes place and this is a vulnerable period in the human life cycle for the development of nutritional anaemia, which has been constantly neglected by public health programs. The prevalence of anaemia is disproportionately high in developing countries than developed countries. It has mainly been ascribed to poverty, inadequate diet, certain diseases, pregnancy and lactation, and poor access to health services in developing countries

BACKGROUND Blood transfusion is the transfusion of whole blood or blood components (packed cells or plasma only) into the blood stream or directly into the bone marrow. 1 It is carried out between individuals with compatible / identical blood groups, failure of which results in adverse transfusion reactions. An ATR (Adverse Transfusion Reaction) is an unfavourable reaction to the transfused blood/ blood component, the severity of which differs from person to person depending on the patient's susceptibility, degree of incompatibility and the type of reaction. 2
