ABSTRACT
Since the major physiological control of erythropoiesis is related to the eryhtropoietin (EPO) level, correlating the EPO level with hematologic parameters in healthy adults, which constitutes an inexpensive and simple routine laboratory report, would be very useful. Two hundred healthy adult blood donors, 100 males and 100 females, aged between 17 and 60 years old were randomly chosen. The EPO reference range was determined by enzyme linked immunosorbent assay (ELISA) using a reagent kit from Research & Development Systems Inc. The hematologic values for reticulocyte and red blood cell parameters were assessed using the Technicon H*3 RTC, an automated blood cell analyzer. The EPO reference range in the studied population was 2.21-20.95 mU/ml. The correlations between the EPO level and hematologic parameters were between -0.302 (p < 0.01) and 0.294 (p < 0.01). The results suggested that there were none or low correlations between the EPO level and hematologic parameters in healthy adults. According to our results, these parameters could not be used to indicate the level of EPO in healthy adults.
