Specialized Features on Advanced Plasma Clot-Based Coagulometers Flashcards
A variety of tests can be performed on a single specimen or multiple specimens in any order as determined by the operator.
Random access
Plasma is directly aspirated from an open or a capped, centrifuged, blood collection tube by the analyzer.
Primary tube sampling
Analyzer aspirates plasma from the closed, centrifuged primary blood collection tube.
Cap piercing
Reagents and specimens are identified with a bar code, eliminating manual information entry.
Bar coding
Analyzer queries the host computer via the LIS to determine which tests have been ordered. After verification results are sent from the analyzer to the host computer via the LIS.
Bidirectional laboratory information system interface
Automated alerts indicate problems with specimen integrity or instrument malfunction.
Specimen and instrument flagging
Operator is alerted when there is inadequate specimen or reagent volume for the number of tests ordered. An alert is also given when the instrument fails to aspirate the required specimen volume. Volume is verified each time a specimen or reagent is aspirated.
Liquid level sensing
Instrument stores and organizes quality control data; may include application of Westgard rules for flagging out-of-range results; instrument may transmit quality control data to the LIS.
On-board quality control
Operator can interrupt a testing sequence to place a specimen next in line for testing.
Stat capabilities
Refrigeration maintains the integrity of specimens and reagents throughout testing; allows reagents to be kept in the analyze
for extended periods reducing setup time.
On-board refrigeration of specimens and reagents
Indicates the number of specimens that can be loaded at a time.
On-board specimen storage capacity
Instrument can be programmed to perform repeat or additional testing under operator-defined circumstances.
Reflex testing
Test results can be stored for future retrieval; clot formation graphs may be included.
Patient data storage
Number of tests that can be processed within a specified interval, (usually number of tests per hour); depends on test mix ano methodologies.
Throughput
Length of time from specimen placement in the analyzer until testing is completed; depends on the type and complexity of the procedu
Total testing (dwell) time
Operator can visualize how the clot is formed over time.
