Hematology quality control and the Ortho ELT-8.

Abstract

In summary, it is our conviction that each clinical hematology laboratory must perform a rigorously controlled primary whole blood calibration of their ELT-8 or other CBC instrument. Commercial controls should be obtained from more than one source, and assayed by each laboratory. The ELT-8 Control Libraries are a convenient electronic medium for storage of these assay values and subsequent accumulation of control runs. The moving average library needs to be configured for mean value and ranges by each laboratory and serves as an extremely sensitive real time monitor of instrument performance as well as a guide to the use of stable commercial controls.
