    This is  an instance of where I was floored by Sylvia's definition of QC as  
    'quality control', a definition I haven't seen  used.
    It all depends on where you are coming from.  As a microbiologist and  state 
    inspector of all sorts of medical laboratories (recently retired) I have  
    spent hours reviewing QC records of daily testing.  The QC test is the  'reality 
    test'.  The answer is always known and if you do a test run and  the QC is 
    within the limits of the known value you can feel assured that the  other sample 
    results were valid.  On the other hand when the QC test  doesn't give you the 
    correct answer, you can assume the whole test run is  incorrect......  And 
    start over.
