reference laboratories • Reference value is the mean of the reference value + 3 standard deviations # Upper limit: Lower limit: reference value - 3 standard deviations a A: Analysis acceptable; Results not reported lower limit, not acceptable H: Results > upper limit, L: Results < (reported result -reference value)/standard deviation 8 2 Score = based on z-scores. Note: the accectabl ity of reported results is this is why a reported result may appear acceptable according to performance l imits, but be identified as an outl ier.
