What if the Frequency of Changing QC is Zero?
We know how to change QC frequency in a data-driven, evidence-based, patient-risk focused way. But we don't seem to be doing it at all.
Establishing Appropriate Risk-Based QC Frequency
Clinical Laboratory News June 2019 issue had an article about QC Frequency. Dr. Westgard was interviewed for that article, plus here are some additional extras that support the piece.
