Food for thought...
“When
you set a financial budget, you know that if you spend too much in
one place, you run over your budget. The analogy for lab tests is an
‘error budget.’ We know we have certain sources of error like
precision and inaccuracy. How much of the budget gets spent by
different error sources, and is it possible that we will overrun the
budget if a problem occurs?”
“Well,
we have information on that, in the form of what quality is required
for the test. If you define that in your budget, then you can measure
the errors for your methods in the laboratory to be sure they fit
within the budget. That should be an ongoing part of quality
management: keeping track of how big these errors are and how they
relate to the amount of error that is allowable.”
