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.
