[Survey and Establishment of the Hematological Parameter Reference Intervals for Adult in Xuzhou Area of China].

Objective: To establish the reference intervals of the hematological parameters in normal adult people of Xuzhou erea.
Methods: The red blood cells (RBC), platelets, white blood cells (WBC) and related parameters were detected by hematoanalyzers in 82514 healthy people including 41257 males and 41257 females in the Medical Center of the Affiliated Hospital of Xuzhou Medical University.
Results: The range of RBC count: (4.33-5.51) ×10 ¹² /L in male and（3.82-4.85）×10 ¹² /L in female, the range of Hb level: (132-172) g/L in male and（107-145）g/L in female, the range of HCT: 40 %-50 % in male and 34 %-44 % in female, the range of platelet count: (113-268) ×10 ⁹ /L in male and (126-289) ×10 ⁹ /L in female, the range of WBC count: (4.00-9.40) ×10 ⁹ /L in male and （3.54-9.30）×10 ⁹ /L in female, the range of NEUT count: (1.91-5.76) ×10 ⁹ /L in male and（1.67-5.30）×10 ⁹ /L in female, the range of MONO count: (0.18-0.58) ×10 ⁹ /L in male and（0.16-0.52）×10 ⁹ /L in female, the range of LYM is（1.3-3.4）×10 ⁹ /L in male and（1.2-3.1）×10 ⁹ /L in female, etc.Conclusion: There is significant difference in the blood cell parameters between Xuzhou and other areas. Among them, the lower limit of Hb reference interval for adult women in Xuzhou area is obviously lower, and the upper and lower limits of adult Plt reference interval are significantly lower than other areas in China and abroad. The upper and lower limits of the WBC reference interval are close to the domestic areas, but lower than that in some foreign regions. Through this survey, the reference intervals of different hematologic parameters of healthy people in Xuzhou area primarily has been established, Some of the indexes, such as RBC, Hb, HCT, and Plt have significant sex differences. The reference intervals for them have been estublisted respectively.
