Abstract: In order to supply a basis for uniting the reference value standard of Chinese healthy adult and young people's whole blood contrast viscosity,a research is made about relationship between the reference value and five geographical factors.It is found that altitude is the main factor affecting this reference value.As the altitude increase gradually,the reference value also increase gradually,the correlation is quite obvious.Applying the method of mathematical regression analysis,two regression equations are given out.If geographical values are obtained in some areas,the reference value of Chinese healthy adult and young people's whole blood contrast viscosity of this area can be reckoned using regression equations.

Key words: reference value, geographical elements, whole blood contrast viscosity, regression analysis, hemorheology
