In this first lesson, Dr. Paulo Pereira introduces some of the basic concepts of method validation that apply when a qualitative method is being evaluated.
Basic Method Validation
CLIA and CAP require continuous calibration verification. Interestingly, the regulations aren't that specific about how to judge whether or not the calibration is successful.
Bias, Accuracy, Inaccuracy, call it what you will. Sometimes your method generates different results than other methods, for example, systematically shifting values high or low. Laboratories must determine if bias exists in their methods, and estimate the severity of that bias.
It's not some new age religion, it's yet another confusing aspect of method validation. This time Dr. Westgard teams up with Trish Barry to explain the ins and outs. (Preview)
When does a test become less useful? Dr. Westgard gets some help from Karen Mugan, Elsa Quam, Trish Barry, and Neill Carey to explain this confusing aspect of Method Validation. (Preview)
