Quality Control of Automated Cell Counters - 11/02/15
, Gwen Clarke, MD, FRCPC bRésumé |
The hematology analyzers of today provide more reproducible analyses compared with those of a few decades ago, necessitating an evolution in hematology quality practices. The improved performance allows use of simple quality control rules. This improved performance also renders the repeat analysis of critical value specimens non value added. Some of the patient averaging techniques have become outmoded and need to be replaced by less complicated calculations but with truncation of predictable outlying populations. The ready availability of comparative peer quality control values helps to improve analyzer precision and accuracy, and simplifies instrument validation and calibration.
