Popis: | This survey introduces the subject of internal quality assessment from a historical point of view, presents a unified approach to notation, concepts and definitions, and describes briefly those quality control procedures that are used most commonly in clinical chemistry. It is not the aim of this report to comment on all the individual contributions made in this field, but rather to concentrate on the principles. Particular emphasis is centered around assessment criteria to compare the efficiencies of selected control procedures for monitoring analyte concentrations in biological fluids. The question of whether to compare control schemes by means of average run lengths, run length distribution functions or average cost functions is considered. A rationalized approach based on the comparison of optimal procedures, using average run length, is adopted. |
