Objective To compare correction on the 7020 and 7180 parts of the project results.Methods Detecting two instrument precision and linearity,then doing Linear Regression Analysis and correction of anterior significant test on 7020 value(y) and 7180(x) measured values,doing linear regression equation of slope,intercepting the instrument correction parameters,inputting 7020 biochemical analyzer,and doing the corrected data check.Results Precision and linearity of 7020 and 7180 is good;glucose,creatinine and creatine kinase levels are consistent.Aspartate aminotransferase levels need to be system alignment correction.Conclusion After contrast correction to 7020,consistent with the 7180 results of the experimental results of the two instruments are comparable.
