Background: Anemia is common throughout the world, remarkably in developing countries. Our aim is to calculate normal hemoglobin and other hematological indices in southwest of Iran.

Materials and Methods: A random selection of 500 healthy males and 500 healthy females was done in the age group of 13 to 65 years. A complete blood count (CBC) was performed in all participants.

Results: Hemoglobin (Hb) level ranged from 13.80 to 18.40 g/dL with a mean value of 15.96 g/dL in males, and 12 to 15.90 g/dL with a mean value of 13.79 g/dL in females. Mean cell volume (MCV) ranged from 80 to 100.10 fL with a mean value of 86.63 fL in males, and 80 to 95.40 fL with a mean value of 86.80 fL in females. Red blood cell (RBC) count ranged from 4.5 to 7.07×10⁶/mm³ with a mean value of 5.57×10⁶/mm³ in males, and 4.17 to 6.84×10⁶/mm³ with a mean value of 4.88×10⁶/mm³ in females.

Conclusion: Although the normal range of various hematological indices of our study nearly were equal to that presented in the literature, some parameters differed such as maximum value of Hb in males, maximum value of hematocrit (HCT) in both sexes, range of MCV in females, and range of mean cell hemoglobin concentration (MCHC) in both sexes. The most prominent feature was the higher maximum value of RBC count in both sexes.
