Quality Management

process by which the laboratory ensures quality results by closely monitoring preanalytical, analytical, and postanalytical phases of testing.

quality assessment/quality assurance

include test requisition, patient preparation, patient identification, specimen collection, labeling, specimen transport, specimen reception, handling, and preparation

pre-analytical

What are the five important process in analytical phase?

reagents, maintenance, calibration, sample analysis, quality control

include verification of calculations and reference ranges, flagging and notification of panic/critical values, delta checks, reporting of results, and interpretation

post-analytical

an algorithm in which a current laboratory result is compared with results obtained on a previous specimen from the same patient

delta check

What type of potential error is indicated?
Instrument not calibrated correctly

analytical

What type of potential error is indicated?
Instrument precision problem

analytical

What type of potential error is indicated?
Incorrect sample volume

analytical

ability to maintain accuracy and precision over an extended period of time during which equipment, reagents, and personnel may change

reliability

closeness of the result to the true or actual value

accuracy

ability to produce a series of results that agree closely with each other; commonly expressed in terms of coefficient of variation

precision

In Internal Quality Control, it involves the analysis of at least ____ levels of control every ____________
