Abstract
To the Editor, Recently sigma metrics have been used to assess assay fitness for purpose using external quality assessment surveys [1, 2]. One of the major decisions facing clinical laboratories is the evaluation and purchase of new equipment. This exercise is a considerable one with the costs of both the initial equipment and ongoing consumable costs having a significant impact on the laboratory budget. Many factors may be taken into account when comparing analysers including hardware and consumable costs, environmental costs (power and water), ongoing training and maintenance support. But perhaps most attention is devoted to the analytical performance of individual assays since poor performance can have deleterious effects on reagent and human resource costs (repeats, recalibration), staff morale, and customer satisfaction in terms of poor turnaround times and inappropriate clinical decisions which can reduce laboratory credibility.
