Background: Anaemia is defined as a decrease in the number of red blood cells (RBC) or the haemoglobin (Hb) content of blood, or a decrease in Hb's ability to bind oxygen. Anaemia in children differs from that in adults in that it is more pronounced and develops more rapidly. In developing regions, up to 51% of children aged 0-4 years and 46% of children aged 5-12 years are anemic. Aim: To evaluateanaemia in paediatric age group using different haematological and biochemical investigations. Material and method: The present study was conducted among 250 patients with anaemia in the age group of 0 to 18 years. Various haematological (CBC, GBP, Bone marrow aspiration, HPLC) and biochemical (Serum ferritin, Serum iron, TIBC, Vit. B12 and Folic acid) investigations were done on the blood samples received. Data so collected was tabulated in an excel sheet and was analysed using SPSS software version 22. Results: Maximum patients were diagnosed with iron deficiency anaemia. 34 patients were diagnosed with vitamin deficiency anaemia (Vit. B12, Folic acid or both). Maximum (26.4%) number of Vit. B12 deficiency anaemia patients were from 13- 18 age group whereas maximum (17.6%) number of Folic acid deficiency were found in 7- 12 years. Conclusion: Anaemia can be detected early using biochemical and haematological assays. Children's anaemia prevention programmes should be established in conjunction with initiatives to meet their dietary needs.
