Aim

This paper aims at supplying a scientific basis for unifying the normal reference value standard of red blood cell count of Chinese young men.

Methods

The research is made to study the relationship between the normal reference value of 41,759 examples of red blood cell count of young men and 8 geographical factors in 334 areas in China, which is determined by the microscopical counting method.

Results

It is found that the correlation of geographical factors and the normal reference value of red blood cell count of young men is quite significant (F = 224.98, P = 0.000). By using the method of stepwise regression analysis, one regression equation is inferred.

Conclusion

If geographical values are obtained in a certain area, the normal reference value of red blood cell count of young men in this area can be reckoned by using the regression equation. Furthermore, according to the geographical factors, China can be divided into eight districts: Northeast China District, North China District, Shanxi-Shaanxi-Inner Mongolia District, Middle and Lower reaches of the Changjiang River District, Southeast China District, Northwest China District, Southwest China District, and Qinghai-Tibet Plateau District.
