LEC: Computers and Specimen Handling and Processing Flashcards
used in healthcare to manage data
Computers
defined as having basic knowledge about computers
Computer literacy
specialized application of information technology to optimize laboratory operations
laboratory informatics
major part of laboratory informatics and it is a customized computer software to record, process, manage, and store data from a variety of workflow processes in the laboratory
Laboratory information system (LIS)
it is phase when most laboratory errors occur
pre-examination/preanalytical phase
PT and PTT tests should be performed within ___ hours of specimen collection
four hours
this should be place in cooling tray, STAT and separated from the cells within 15 minutes of collection
AMMONIA SPECIMENS
this is stable for 24 hours at room temperature and for up to 48 hours when refrigerated at 4 to 8 Celsius
GLUCOSE SPECIMENS IN SODIUM FLUORIDE TUBES
this should be tested as soon as possible because it is difficult to inhibit glycolysis
PEDIATRIC GLUCOSE SPECIMENS
must be prepared within one hour of collection
(EDTA) Blood smears
analyzed within 6 hours but are generally stable for 24 hours at room temperature
EDTA specimens for CBCs
must be tested within four hours if left at room temperature or within 12 hours if refrigerated
EDTA for ESR
stable up to 6 hours at room temperature and up to 72 hours if refrigerated
EDTA for reticulocyte counts
If an RNA test must wait to be run in a batch, the plasma can be stored at __ Celsius but only for __ hours.
4C & 48 hrs
If the plasma is not tested within that timeframe, it must be transferred from the PPT to an aliquot tube and frozen at ____
-80 Celsius
