GLOSSARY
Extended QC -
Random Error Random error is Extended QC’s measurement of imprecision.
Extended QC -
Systematic Error Systematic error is Extended QC’s measurement of bias. A systematic error is
defined as the deviation of the mean from the target value.
Extended QC - Total
Error Total Error is Extended QC’s measurement of inaccuracy, as compared to an
established limit.
Total Error is defined as the deviation of a single measurement from the Target
Value that was setup for your 5C Cell control (e.g. BCI Assigned Value or Mean
=> Lab Target value) .
Field Area on a window or screen for entering or viewing data. When you move the
cursor, you are moving it from field to field.
First Name Referes to the patient’s first name. The Workstation considers this field an
optional identifier you can use for a sample. The 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.
fL
Femtoliter, a unit of volumetric measurement equal to liter.
Flags A flag is a single letter or symbol and will always appear to the right of a result.
A flag can be instrument-generated (R, P), or laboratory-defined (H, L, c, a). On
windows and printouts, the letters, such as H, L ,and R appear next to
parameter results to indicate specific conditions.
Flow Cytometry A process for measuring the characteristics of cells or other biological particles
as they pass through a measuring apparatus in a fluid stream.
Function Key One of the keys labeled F1 to F12. To request a system or window-specific
command, press the Function Key displayed on the screen next to the
command. Sometimes these keys are used with other keys to access specific
functions.
g Gram, a unit of weight.
HCT (Hematocrit) A computed value that represents the packed cell volume (PCV) relative to a
given volume of whole blood.
HCT (%)= (RBC x MCV) / 10
Hemoglobinometry Measurement of hemoglobin in the blood. In the LH 700 Series, this is done by
comparing the amount of light that passes through a diluted lysed sample, in
which the released Hgb has been chemically converted, with the amount of light
that passes through a blank (diluent).
HGB (Hemoglobin) Hemoglobin results from the CBC analysis. This parameter is measured directly
using Photometric Measurement.
Hgb Voltages Electronic voltages measured through the hemoglobin cuvette.
