erudite Flashcards
includes procedures such as laboratory handling
and identification, which take place prior to any laboratory testing. In this phase, proper
control measures are placed to avoid subsequent issues.
pre-analytical testing phase
pre-analytical testing phase starts when and ends when??
It starts when the doctor’s order is
given and ends when the laboratory testing has officially commenced.
During this phase, the phlebotomist must not only be able to draw blood from the patient, but must also be able to identify factors that affect the process and address them as
needed.
pre-analytical testing phase
The ___ is used by physicians to diagnose and monitor the presence of a
disease.
laboratory test
The physicians compare the results to a ________ or _________ This
range shows the high and low limits of result values as compared to healthy individuals.
reference range or reference interval.
This range shows the high and low limits of result values as compared to healthy individuals.
Reference range or reference interval.
This can be influenced by age, gender, and conditions of the body.
