Provisional Kuwaiti Children Hematology Reference Range

Introduction: Hematology reference ranges (HRR) in the third world countries usually based on results of measurements in advanced countries. Our HRR based on UK HRR since more than 5 decades. However, these parameters are affected by several factors including age, ethnicity, gender and environment. The goal of this study is to establish a provisional HRR for Kuwaiti children (CPK-HRR) and compare it with UK children hematology reference range (CUK-HRR). Method: The blood results of 1200 normal child were collected from electronic data of 95,501 children and adults Kuwaiti. The children divided into 8 groups according to age and gender. The range of the RBC, Hb, Hct, MCV, MCH, MCHC, RDW, WBC count, ANC, lymphocyte, monocyte, eosinophil, and basophil counts, PLT count, PMV, were evaluated to generate CPK-HRR. Result: The Kuwaiti children HRR in their early life were insignificantly different from UK children HRR but from the age of 13 years old up to the entire adult life, the differences between the two populations became clearly significant. Conclusion: Kuwaiti pediatric population is different from UK pediatric population in the complete blood count parameters. This study supports the results of our previous adult provisional HRR. Generating regional children HRR is essential for proper diagnosis, treatment, and research work.
