Lesson 4: How do you build quality into a laboratory testing process?
In Putting Quality into Quality Control, Dr.
Westgard emphasizes the need for quality planning, with particular attention
to selecting statistical QC procedures that are appropriate for detecting
medically important errors. Four practical approaches for QC planning are
identified in Starting a QC Planning Process. A detailed
example of QC planning using analytical quality requirements is provided
for a Cholesterol test subject to CLIA proficiency testing.
Another example considers a Cholesterol test and a clinical quality
requirement based on NCEP guidelines for interpretation of a screening
test. |
