We will use a live simulator to model changes in method accuracy and precision - and Q.C. design.
Which chart shows the biggest change?
  
Is there a positive bias after the shift?
What Q.C. rules would be broken?
How many runs would be reported before the first QC flag?
How many patients would receive lab errors?


Two Q.C. Charts
 
Calling all Sodiums!  
Verify the effectiveness of your Q.C. practices to detect clinically-significant change.
Send this quick information in the
attached Excel file.   (Create your own 4-digit code.)
The simulator lets us model different types and sized of change.
   See it live with real data!

Please note.  I am not being critical of any individual person, institution or organization.  I want to express my most sincere respect, admiration and appreciation to  Dr. Westgard and so many others.  This process does not contradict  today's  published  recommended, principles and processes; it just implements them differently.
