为制定我国老年人红细胞压积参考值的统一标准提供科学依据,收集我国各地用温氏法测定的健康老年人红细胞压积参考值,并对其与海拔高度的关系进行了研究,发现随着海拔高度的逐渐增大,红细胞压积参考值逐渐增大,相关性很显著,用一元回归分析的方法推导出了2个回归方程,如果知道了我国某地的海拔高度,就可以用回归方程估算这个地区的老年人红细胞压积参考值。
To provide a scientific basis for the development of a unified standard for the reference value of the elderly hematocrit in our country and to collect the reference value of hematocrit of healthy elderly people measured by the Wen’s method in different parts of our country and to study the relationship with the altitude above sea level The altitude increased gradually, the reference value of hematocrit gradually increased, and the correlation was significant. Two regression equations were deduced by the method of univariate regression analysis. If we know the altitude of a place in our country, we can use the regression equation Estimate the reference value of the hematocrit for the elderly in this area.
