Clinical Chemistry Automation 9th
Edition by Bishop Fody Questions &
Answers with rationales
automation - ANSmechanization of the steps in a procedure, manufacturers of clinical chemisry
analyzers design their instrument to mimic the manual techniques in an analytical procedure
bar code - ANSa set of vertical bars of varying width used to encode information; used most
frequently in the clinica laboratory for the patient and specimen information
centrifugal analysis - ANSanalytical technique that uses the force generated by centrifugation to
transfer and then contain liquids in separate cuvets for measurement at the perimeter of a
spinning rotor
channel - ANSon an autoated analyzer, a path or passage for reagnets, specimens, or electrical
impulses
closed tube sampling - ANSan instrument's ability to remove the patient's sample for analysis
from the primary collection tube by piecrcing through the stopper
continuous flow - ANSan approach to automated analysis in which liquids (reagents, diluents,
and samples) are pumped through a system of continuous tubing, samples are introduced in a
sequential manner, following each other through the same network, a series of air bubbles at
regular intervals serve as separating and cleaning media
discrete analysis - ANSan approach to automated analysis in which each sample and
accompanying reagents is in a separate container; have the capability of running multiple tests
one sample at a time or multiple samples on test at a time
dry chemistry slide - ANSa multilayered film technology (dry chemicals) used by the Vitros
series of automated analyzers; all reagents neccessary for a particular test are contained on the
"slide"
flag - ANSon automated analyzers, a computerized printed warning of an error or instrument
problem
