The History of Statistical Quality Control in Clinical Chemistry and Haematology (1950 – 2010)
Statistical quality control in clinical chemistry and haematology has a tradition of almost 60 years. The most important landmarks were the adoption of control charts by Levey and Jennings (1950), the use of different control levels by Henry and Segalove (1952), the preparation of specific control samples by Freier and Rausch (1958) and the invention of control rules by Westgard et al (1981).

Automated quality control for the haematology laboratory.
Two simple methods of using sophisticated statistical techniques to analyse intralaboratory quality control data are described. One method uses a plastic grid to assess the cumulative sum (cusum) graph. An equivalent procedure, which may be carried out by a laboratory computer, gives automated on-line quality control of the Coulter S blood counter. The possible development of simple apparatus t...
متن کاملQuality control in haematology: report of interlaboratory trials in Britain.
An interlaboratory quality control scheme has been established in Britain by the British Committee for Standards in Haematology. In the first instance this has been confined to haemoglobin, red blood cell count, and packed cell volume. The materials which have been circulated include whole blood, stabilized red cell preparations, lysates, cyanmethaemoglobin solutions, and cyanmethaemoglobin ref...
