Abstract
In order to provide a scientific basic for a unified standard of the reference value of old people's erythrocyte sedimentation rate (ESR) in China. The reference value of healthy old people's ESR was collected according to the Wintrobe method, the relationship between the reference value of old people's ESR and altitude was tested in this paper. It was found that the reference value of old people's ESR decreases when the altitude gradually increases, the relationship is quite significant. The method of mathematical univariate regression analysis was used to deduce two regression equations: Y1 = 16.38 - 0.00301X +/- 6.53, Y2 = 25.92 - 0.00438X +/- 10.25. If the altitude value of a particular area of China is known, the reference value of old people's ESR can be calculated by means of the regression equations. Furthermore, depending on the altitude, China can be divided into three districts: Qingzang Districts, Central Districts and Eastern Districts.
