GLOSSARY-2
GLOSSARY
AutoCollation A Workstation feature that automatically combines results of different test
modes (CBC/Diff and Retic) analyzed from a sample with an identical patient or
sample ID. The different test modes must be performed within a predetermined
time.
Automatic Aspiration
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.
Automatic Startup
Cycles When you press the Startup button, the system flushes the cleaning agent from
all Diluter components and tubing if cleaning reagent is not already removed. It
also performs electronic and fluidic checks to ensure the instrument is ready to
analyze control or whole-blood samples.
AutoNumbering A Workstation feature that assigns a number to each sample received from the
instrument.
Autopurge If 24 hours elapse with the power on, pneumatics off, and the instrument in
shutdown, the system automatically turns on the pneumatics; drains and fills
the baths; and purges the flow cell and associated sample lines with cleaning
agent.
AutoSequencing A Workstation feature used with the ToDo list to automatically increment the
identifiers you specify (Patient ID, Cass/Pos, sample ID, and sequence number).
AutoStop A Workstation feature that instructs the instrument to stop processing based on
specific criteria.
Average Value A value that is computed by dividing the sum of a set of values by the number of
values. Usually referred to as the simple arithmetic mean.
BA # (Basophils) A WBC differential parameter result from the Diff sample analysis. The number
(#) is computed from the WBC count and the BA %.
BA % (Basophils) A WBC differential parameter result from the Diff sample analysis. The percent
(%) is measured directly using VCS technology.
Background Count A measure of the amount of electrical or particle interference using a diluent
sample or no sample.
Background Results Background results indicate reagent quality and the presence of electronic noise
or bubbles. Background results above certain levels cause concern since they
might falsely elevate (or interfere with) the results obtained for blood and
control samples.
Batch A group or set of results.
r
For Xb Analysis, a batch equals 20 patient samples used for monitoring
MCV, MCH and MCHC as an automated QC procedure.
r
For XM Analysis, a batch can contain 2 to 1,000 samples used for
monitoring any parameters.
r
For printing or transmitting, a batch equals the samples you selected from
the database.
