Hematological Reference Ranges for Healthy Adult Males in the Central province of Iran

Background:Laboratory reference values are an important tool for clinical management of patients.Reference values being used in most laboratories in Iran have been provided from theestablished reference values from developed countries. However, several variables can affecton these laboratory parameters. Therefore, this study was carried out to establish thereference values of hematological parameters in the blood donors of Central province of Iranas a general populationMaterials and Methods:Blood samples of 1100 male blood donors were collected consecutively from BloodTransfusion Organization. Complete blood cell (CBC) count and differential was performedusing an automated hematology analyzerResults:The median and 95% reference values (2.5th-97.5th) for Hb and platelet counts were 15.5g/dl (14.1-17.7) and 209 ×109 cells/L (151-322) respectively. The median for total WBCcount, neutrophil, lymphocyte, monocyte and eosinophil were 6.7 ×109 cells/L (4.3-11.2),%58 (%50-%70), 40% (30-49%), 0% (0-2) and %1 (0-3%) respectivelyConclusion:Our study revealed that the hematological profile of the population in central province of Iranwas different from the reports of other countries and also the standards reference rangesdescribed in textbook. So, further nationwide study should be carried out to establish thehematological reference values of the Iranian population as a whole.
