hematological parameters are vital in diagnosis، treatment and monitoring of many disease and health conditions. But the reference values of these parameters are influenced by various factors including race، environmental and physiologic conditions. Referring to others reference intervals or indetermination the intervals for specific populations may causes the irreparable injuries and this is of specific importance in pregnant women due to the importance of mother and fetus health. This study was performed with aim to determine the reference values of complete blood counts (CBC) during third trimester of pregnancy in Dorud.

this cross-sectional study was performed on 351 pregnant women referred to Narges hospital at Dorud city in 2013. A blood sample was taken from each individual with EDTA anticoagulant. Blood cell count، hemogolubin، hematocrit and red blood cell indices were determined using a cell counter sysmex caliber. The leulocyte differential count was performed by providing the peripheral blood smear. The data analysis was performed using SPSS software (version 15)، variance analysis، and chi-square test.

Mean Hb concentration as a factor that was analyzed in many studies was 13. 02 gr/dl in this study. Also mean White Blood Cell and Platelets cell concentration were 10. 16 and 213 (p>0/05).

the changes in the measured factors are similar to other studies. But، the reference intervals were different، meaning that different areas may have different reference intervals for blood factor determination. Therefore، this study needs to be conducted in different parts of country.
