Normal Red Blood Cell Count Reference Values in Chinese Presenile Women Given by Geographical Area

摘要

We aimed to standardize the normal reference value of red blood cell (RBC) counts in Chinese presenile women using an underlying scientific basis. Methods: This research was conducted to study the relationship between the normal reference value of 31,405 RBC samples from presenile women in eight different geographical areas in China. RBC counts were determined using a microscopic counting method. Results: There was a significant correlation between geographical factors and the normal reference RBC value in presenile women (F = 187.82, p = 0.000). Using stepwise regression analysis, one regression equation was obtained. Conclusion: If geographical values are obtained in a certain area, the normal RBC reference value in presenile women in this area can be obtained using the regression equation.
