CLINICAL CHEMISTRY, Vol. 34, No. 6, 1988 1357 The index, of fiduciality is therefore equal to (CVi + CV)’/0.5 when it is <1.00 a method surpasses the goal and when it is >1.00 a method is analytically unsatisfactory. As an example, the following tabulation shows the index calculated from the median precision and comparative bias achieved (May to August, 1986) in the Australasian general serum chemistry quality-assurance program (5) for serum urea (analytical goal: CV ‘c6.3%) with the major instrument groups used.
