GLOSSARY
Histograms Graphic representations of cell frequency vs. size. Histograms provide
information about leukocyte, erythrocyte and thrombocyte frequency and their
distribution about the mean. They also might show the presence of
subpopulations.
Hz Hertz, a unit of frequency.
i.d. Inside diameter.
IEC International Electrtechnical Commission.
Information System Any host or laboratory computer system.
Instrument The Analyzer and Diluter portion of the LH 700 Series.
IQAP
(Interlaboratory
Quality Assurance
Program)
Beckman Coulter Inc. provides this program, which statistically compares your
5C Cell control and Retic-C Cell control data to a group of other laboratories'
control recovery data with the same control lot number.
IRF (Immature
Reticulocyte
Fraction)
This parameter is derived from VCS technology.
IRF = High Light Scatter Reticulocytes / Total reticulocytes
L Liter, a unit of volumetric measurement.
Lab Administrator A person at your location who can access the full set of Workstation functions.
The lab administrator creates user names and assigns access levels. A specific
user name and password is assigned to the lab administrator in your laboratory.
Laser (Light
Amplification by
Stimulated Emission
of Radiation)
The instrument uses a laser for WBC Diff and Retic analysis.
Last Name Referes to the patient’s last name. The Workstation considers this field an
optional identifier you can use for a sample. This field appears blank unless you
provide the information when you add a sample request to the ToDo list or edit
a sample result on the Edit Sample window.
Levey-Jennings
Control Chart
A commonly used control procedure in which control measurements are plotted
directly on a control chart with limit lines drawn as mean plus or minus
expected ranges.
Linearity The ability of an instrument to recover expected results (reference values or
calculated values) for such parameters as WBC, RBC, Hgb and Plt at varying
levels of concentration of these parameters within specified limits.
Beckman Coulter Inc. provides the LIN-C linearity control for your
convenience. Use it according to the instructions on its package insert.
Lot Number An identifier assigned by a manufacturer to identify a control, reagent or
calibrator.
LY #(Lymphocytes) A WBC differential parameter result from the Diff sample analysis. The number
(#) is computed from the WBC count and the LY %.
