AUTOMATION Flashcards
Laboratory automation is the process by which an instrument automatically performs tasks
AUTOMATION
Now described as a broader process wherein multiple devices, often linked together by Laboratory Information System (LIS), are capable of automating pre-analytic, analytic, and post-analytic phases of testing.
AUTOMATION
- Specimen is aspirated through the sample probe into a continuous reagent stream
- Reagent is pumped through a system of continuous coiled tubing which is responsible for the mixing of the reagent and
sample
CONTINUOUS FLOW ANALYZERS
Samples will flow through a common pathway and reactions are separated via air bubbles
CONTINUOUS FLOW ANALYZERS
specimens are separated by air bubbles allowing batch analysis to be performed
Batch analysis
What is the primary source of Continuous flow analyzers?
Carry over
presence of remnant of previous sample that affects succeeding sample
Carry over
Uses a spinning rotor to generate centrifugal force to transfer and contain liquids in separate cuvettes for analysis
CENTRIFUGALL ANALYZERS
Transfer reagents and samples by virtue of acceleration and deceleration of sample
CENTRIFUGALL ANALYZERS
Capable of performing one test on multiple samples
CENTRIFUGALL ANALYZERS
Most popular and versatile
DISCRETE ANALYZERS
Each sample and the corresponding reagent are handled separately in its respective reaction vessel
DISCRETE ANALYZERS
Runs multiple tests on one sample or one test on multiple samples
DISCRETE ANALYZERS
Performs random access; batch and sequential analysis
