8 - Putting TEa into Quality
To control quality, one must first determine what quality is needed for a test. In this activity, participants will explore what information the fourth key number must provide to define the quality required. Additionally, participants will use a laboratory scenario to assess if the method remains acceptable for the intended clinical use of the test result.
- TEA defines the quality specifications specific to the analyte being tested to make the analytical result clinically meaningful.
- QC statistics can effectively reflect method performance if acceptable performance limits are defined and applied.
- For clinically meaningful results, the TE should be less than the TEA for that analyte.
- Identify the four key numbers needed for quality?
- Calculate error limits if given the Target Value and TEA?
- Compare TE to TEA to determine if the method still performs within acceptable limits?
