GLOSSARY
Batch Mean The mean or average of a set of samples. For Xb and XM Analysis, the batch
mean is a value based on a statistical averaging technique and is a type of
"weighted moving average." It is used to estimate what a simple average result
of a very large number of samples (population mean) might be by using a small
number of samples.
Batch Print Job Selecting multiple items from the database, then selecting the print icon to print
all of them at the same time.
Baud A rate defining how many data bits per second are transferred during
communications between two pieces of equipment.
Calibration A procedure to standardize the instrument for accuracy by determining its
deviation from calibration references and applying any necessary correction
factors.
Calibration Disk A data diskette containing the Assigned Values for the lot number of the S-CAL
calibrator kit being used.
Calibration Factors Values the system uses to fine-tune instrument accuracy.
Carryover The percentage (WBC, RBC, Hgb and Plt) or particle count (for Diff and Retic)
of blood cells that are retained from one sample to the next.
Cass/Pos The Workstation considers this field an optional identifier for the cassette
number and cassette position number. This identifier appears on bar-code labels
so that cassettes and positions are automatically read using a bar-code reader.
Cassette The cassette is the carrier for the sample tubes (patient, control, or special test)
used in Automatic aspiration mode where automatic loading, mixing, and
sampling occurs.
Cassette Clips Clips that you permanently install in each opening of the special cassettes for
tubes with HEMOGARD Closure. These clips allow the special cassette to
accommodate additional types of tubes.
CBC (Complete
Blood Count) A measure of the cell number and the indices. CBC includes WBC, RBC, Hgb,
Hct, MCV, MCH, MCHC, Plt, MPV and RDW
CDC Centers for Disease Control and Prevention.
CEE Commission for Electrical Equipment.
Cell Control A preparation made of human blood with stabilized cells and surrogate
material. It is used for daily instrument QC.
Characters All letters A-Z and numbers 0-9.
Check Valve A one-way valve that routes liquid or air through the Diluter.
Also called: mono-flow valve, one-way valve
CLIA Clinical Laboratory Improvement Amendments.
Closed-vial Mode The closed-vial method of running a sample. You place a closed tube sample in
a cassette and place the cassette on the LH 700 Series loading bay. The LH 700
Series automatically reads the cassette label and tube label (if present) and
aspirates the sample.
Also called: closed-vial mode, primary mode, automatic sampling mode.
