Question

Method validation includes studies of precision and accuracy of a proposed method. How would you validate precision and accuracy?

Expert Solution
validation of precision
 

 

 Precision

Precision of a method is the degree of agreement among individual test results when the procedure is applied repeatedly to multiple samplings.

Precision is measured by injecting a series of standards or analyzing series of samples from multiple samplings from a homogeneous lot. From the measured standard deviation (SD) and Mean values, precision as relative standard deviation (% rsd) is calculated.

%rsdorCV=SDMean×100%rsdorCV=SDMean×100E1

The raw data for precision will be recorded in the approved format and the acceptance criteria for precision will be given in the respective study plan or amendment to the study plan.
