BACKGROUND: Values of hematological parameters are affected by factors such as age, sex, ethnic background and social, nutritional and environmental factors. The objective of this study was to determine the values of hematological parameters, red cell indices and @entity13554 and Hb F levels in normal Saudi @entity1 , living in the Central Province of Saudi Arabia. MATERIALS AND METHODS: The study was carried out on 1526 apparently healthy @entity1 , with ages ranging from 1-15 years, and selected during a household screening program. Hematological parameters, red cell indices, and hemoglobin types ( @entity13554 and Hb F) were estimated, and the @entity1 were divided into 15 groups depending on the age. Male and female @entity1 were separated, and the mean and standard deviation of each parameter was calculated for each age group. RESULTS: No significant differences were observed in the red cell count in the male and female @entity1 . White blood cells gradually decreased from 2 years onwards, while hemoglobin and hematocrit levels increased significantly from 2 to 15 years. Mean cell volume and mean cell hemoglobin also showed slight increases, while mean cell hemoglobin concentration remained more or less constant. Hemoglobin A2 and Hb F showed slight but nonsignificant fluctuations. Comparison of the results with those reported in the literature shows that Saudi @entity1 have some values similar to Caucasians, while others have values which are intermediate between Caucasians and African @entity1 . CONCLUSION: The values reported in this study can be used as normal reference values for Saudi @entity1 and adolescents.

Normal reference values for hematological parameters, red cell indices, XXXX and HB F from early childhood through adolescence in Saudis.
