Methods In the conventional internal quality control in the control specimens after the test day, a specimen which total protein result was 60-80 gL^(-1), and albumin result was 30-50 gL^(-1) was selected from the first ten specimens every day, the specimen's TP and ALB results were retested after 3 hours. The difference between the two test results and the difference of the standard deviation were calculated every day for 40 days. Extreme difference quality control chart was established by control limits of range which was calculated by the standard deviation.

First, we discuss several theories of risk measures respectively such as theories ofcoherent measures of risk, spectral measures of risk and distortion measures of risk.Within the framework of these theories, we discuss and compare standard deviation,mean absolute deviation, lower partial moment, Ginis difference, VaR, CVaR and soon. We conclude that CVaR is superior to other measures with respect to theoreticalproperties.
