Accuracy: The quality control product is used for measurement. The average value of the measurement results should be within the range of quality control target values.
Precision: a, repeatability: The coefficient of variation(CV %) of the measured value should not be greater than 10 % with the same quality control or serum sample repeated 10 times.
B, interbatch difference: The interbatch difference for randomly selecting three batch kits should ≤ 10 %.
Linear: in[ 20,600] In the mg/L range, the linear correlation coefficient R ≥ 0.99, in[ 20,100] The linear deviation within mg/L should not exceed ± 10 mg/L in(100,600] The determination deviation within the mg/L range should not exceed ± 10 %.
Sensitivity: When the sample concentration is 150 mg/L, the absorbance varies from 0.0200 to 0.1500.
