AUTOMATION Flashcards
Number of tests that can be performed on instrument.
Test Repertoire
Second generation segmented flow analyzer that uses 2 millimeter identifying glass tubing and pumps reagent at flow rates of 2-3 mm per minute.
Technicon Autoanalyzer II (AAII)
TERMINOLOGIES:
Contamination of sample
Carry-over
ADVANTAGE OR DISADVANTAGE?
Rapid Result
Advantage
Capable of running 6 tests at 60 samples per hour.
SMA 6/60
ADVANTAGE OR DISADVANTAGE?
The medtech is discouraged from making observations and using their own judgment about potential problems
Disadvantage
Part:
Holds the cups containing the standards and specimens for analysis, which are introduced into the analytical system by means of aspiration, in a preset sequence and a pre-selected rate.
Sampler
- All samples are carried through the same analysis pathway.
- All samples automatically pass from one step to another without waiting to bring the samples to the same stage of completion.
- The reactions are not necessarily carried to equilibrium since samples and standards are treated exactly alike.
Continuous Flow System
The ability of the operator to program the instrument to perform other tasks while the instrument processes the tests.
Walk-Away Capability
DESIGN:
Performs numerous test but only for a single specimen
Parallel Analyzer
TERMINOLOGIES:
Amount of serum that cannot be aspirated
Dead Volume
Capable of running 12 tests at 60 samples per hour.
SMA 12/60
TERMINOLOGIES:
Amount of time to generate one result
Turnaround
Only performs requested test
Selective
ADVANTAGE OR DISADVANTAGE?
Many systems are impractical for small number of samples
Disadvantage
ADVANTAGE OR DISADVANTAGE?
Better Precission and accuracy
Advantage
Capable of running 40 tests at 120 samples per hour.
SMAC
TERMINOLOGIES:
Mechanism for patient/sample identification; used for reagent identification by an instrument
Bar Coding
The number of test result that are generated by a laboratory during a given time period.
Workload
The lowest value that can be reliably be detected by a method without providing a false positive result.
Sensitivity
DESIGN:
Performs only one test at a time
Sequential Analyzer
Uses an an electrical signal from the sensor, as a from the photoelectrical cell and compares it with a reference signals as for the blank solution
Analog Computation
A well designed automated system maintains or reproduces the prescriibed conditions with great precision.
Standardization
ADVANTAGE OR DISADVANTAGE?
Errors in calculations and transcription are reduced
Advantage
