In the early 1990s, a group of European scientists fromed to recommend the best targets for imprecision, inaccuracy, and total error (calculated from biologic variation). This became called the "European Biologic Goals and Calculated Biologic Allowable Total Errors." While later eclipsed by the work of Dr. Carmen Ricos et al (the biodatabase desirable specifications), these quality requirements remain an important resource.

This table contains information on Clinical quality requirement that describe medically important changes in test values, or Decision Intervals (D_int) expressed as a percentage change at a certain Decision Level (D_int = change divided by decision level multiplied by 100 to give a percentage). The sources of the decision intervals presented here are the paper by Skendzel, Barnett, and Platt and a series of recommendations for lipid tests from the National Cholesterol Education Program (NCEP).
