Chapter 12 Flashcards
This organization develops standards for handling and processing
CLSI
Once a specimen is collected what happens next
Specimen collection is verified
Proper specimen handling begins
When the physician orders the test
Clsi and osha do not require
Shock resistant bags
An aliquot is
Portion of specimen being tested
To avoid airborne infection while processing specimen
Remove stoppers behind a splash shield
According to CLSI which tubes should be placed upright as soon as they’re mixed
Non anticoagulant gel tubes
An example of a preanalytical error made at time of collection
Failing to mix tubes
A preanalytical error related to specimen storage is
Exposure to light
An error related to specimen transport
Agitation induced hemolysis
A glucose specimen in sodium fluoride is generally stable for
24 hours
Computerized analyzers in the lab can read bar codes and ID patients if
The label is correctly placed on the tube
Interface means
Interacting through a connection of computers
If a specimen has inadequate information the processor may request
The phlebotomist obtain a new sample
An order inquiry
Retrieves all tests ordered on a patient
Output is
Processed data printed on paper
An example of preanalytical error happening during processing is
Inadequate centrifugation
In specimen handling it’s important to note
Effects of mishandling are not always obvious
Which specimen must be transported on ice
Ammonia
Processing specimens requires a lot of PPE but this isn’t necessary
Shoe covers
To process date you must
Press the enter key
Rough handling during transport will cause many issues but not
Elevate WBC counts
Chilling can cause wrong results for this analyte
Potassium
A two hour time delay does not affect this test
Pregnancy test
