Background: To establish reference intervals for routine blood parameters of healthy Mongolian children in the Inner Mongolia Daxingan region.
Methods: Venous blood samples from 468 children aged 7 - 13 years were analyzed with a Sysmex XE-5000 Automated Hematology Analyzer. Statistical analysis was used to compare findings with the National Clinical Laboratory Procedures and to analyze according to gender and ethnic group.
Results: The reference range for each blood cell parameter is as follows: WBC (× 109/L): 3.44 - 9.27 for males, 3.79 - 9.79 for females; RBC (x 1012/L): 4.25 - 5.36 for males, 4.20 - 5.21 for females; HGB (g/L): 118 - 149. HCT (%): 34.9 - 43.4; MCV (fl): 75.1 - 88.2 for males, and 76.6 - 90.6 for females; MCH (pg): 25.5 - 30.3 for males, and 25.7 - 31.0 for females; MCHC (g/L): 327 - 356 for males, 323 - 353 for females; PLT (109): 109 - 209; NEUT %: 34.6 - 71.9; LYMPH %: 19.8 - 56.8; MONO %: 2.8 - 9.5 for males, and 3.1 - 7.9 for females; EO %: 0.0 - 3.6; BASO %: 0.0 - 1.0 for males, and 0.0 - 0.9 for females. There were significant differences between genders with respect to the WBC, RBC, MCV, MCH, MCHC, MONO %, and BASO % parameters (p < 0.05), but not other parameters (p > 0.05).
Conclusions: The blood parameters of children can vary with geography, nationality, gender, and other variables. Therefore, it is necessary to obtain reference intervals for Mongolian children according to their gender and age.
