GLOSSARY
CLSI Clinical and Laboratory Standard Institute formerly known as the National
Committee for Clinical Laboratory Standards (NCCLS).
cm Centimeter, a unit of linear measurement.
Codes On windows and printouts, symbols, such as -----, ++++, :::::, appear with or in
place of sample or control results because of irregularities. A code can only be
generated by the instrument.
Coefficient of
Variation An expression, in percent, of data spread as related to the mean.
%CV = (SD/Mean) x 100
Coincidence More than one cell within aperture-sensing boundaries at the same time. The
system counts only one pulse and automatically corrects results for
coincidence.
Collation The process of combining the results of different test modes(CBC/Diff and
Retic) analyzed from the same sample.
Command Center A teal bar that appears at the bottom of the screen.
Control Disk A data diskette that contains the assay values for the lot number of the control
being used.
Coulter Principle A method of counting and sizing cells by detecting and measuring changes in
electrical resistance when a particle in a conductive liquid goes through a small
aperture.
Critical Limits Values established by your laboratory to flag results requiring immediate action.
CSA Canadian Standards Association.
CSF Cerebrospinal fluid is a clear, colorless, non-cellular fluid that circulates over
the brain and spinal cord.
Cursor On the screen, a place shown by a little blinking indicator or by a highlighted
area. The cursor shows where you can select an option or type information.
CV (Coefficient of
Variation) An expression, in percent, of data spread as related to the mean.
%CV = (SD/Mean) x 100
Cycle Counter A number that appears on the Analyzer MAIN MENU screen that represents the
actual number of instrument cycles that have occurred.
DataPlot A graphic representation of results. DataPlots present a combined view of
population density and membership. Colors represent different types of cells.
Shades of colors represent the number of cells--bright colors are the most dense.
Data Management
System (DMS) The computer hardware and software that controls instrument operation;
displays, stores, and recalls sample data; automates QC and calibration
procedures; and assists you in troubleshooting.
Also called: ADMS, DMS, LH Workstation.
Default A setting the instrument uses automatically. For example, you can set up a
default printer. Every time you print sample results, the Workstation
automatically prints the sample results to the default printer.
