Parasitic infections and allergies are the major contributing factors of eosinophilia. Aims and Objectives: To study the various haematological parameters of school going children and to find out the correlations between the haematological parameters. Materials and Methods: The study was carried out on 130 students of a secondary public school of rural area of Nashik district. The haematological samples were processed on fully automated 5-part haematology cell analyzer. Eosiniphilia was divided into: mild: 351-1500/mm3 of blood, moderate: 1500-5000/mm3 of blood, severe: >5000/mm3 of blood. Statistical analysis of the various haematological parameters was done subsequently. Results: Eosinophilia was present in 45.38% of children. Total leucocyte count (White blood cell count/ WBC/TLC) was normal in 95.38% children. Mild to moderate anaemia was seen in 66.9% children. Conclusion: Eosinophilia is common among the school going children in our study.
