1.6 Hierarchy (QC only)

Question 1

Quality Control

A system for verifying and maintaining desired level of quality in an individual test or process. These are techniques and procedures that monitor ________________.

Answer 1

performance parameters

Question 2

Quality Control

Statistical process used to monitor and evaluate the analytical process that produces results. Generally, these are __________ techniques that monitor particular sources of errors, estimate the magnitude of the errors, and alert laboratory personnel when indications suggest that quality has deteriorated.

Answer 2

quantitative

Question 3

Quality Control

• emphasizes ________ control procedures but also includes non-statistical check procedures, such as _______ checks, reagent and __________ checks and temperature monitors

Answer 3

statistical; linearity; standards

Question 4

Quality Control

It is classified into two:

Answer 4

1. Internal Quality Control
2. External Quality Control

Question 5

Quality Control: Internal Quality Control

• used to establish the stable performance of an ______ system and assure that patient results are reliable
• These are processes that we do ______ our own laboratories such as regular running of control materials. It is necessary for the daily monitoring of the precision and accuracy of the analytical method.
• It detects changes in ___________ only between the present operation and the stable operation that was
  characteristic during the baseline period when the analytical method was thought to be operating properly.
• can detect both _______and _______ errors in the analytical system. This is otherwise known as _____________.

Answer 5

assay; within; performance; random; systematic; intra-lab
QC

Question 6

Quality Control: External Quality Control

• provides a medical technologist with a tool to evaluate his own laboratory performance in relation to other laboratories
• Common applications of this process are participation in _________________ and ______________
• ______________ are available to laboratories, some sponsored by professional societies and other offered by manufacturers of control materials
• ______________are a type of external quality assessment in which simulated patient specimens made from a common pool are analyzed by the laboratories enrolled in the program. Results are returned to a central facility and are evaluated to
  determine the quality of each laboratory’s performance.
• Government and licensing agencies are increasingly using ________ as an objective method for accrediting laboratories, thereby giving them official authorization to operate.
• In general, the performance characteristics of PT programs for detecting bias are evaluated using methods similar to those used in IQC.
• this is important for maintaining _______ term accuracy of the analytical methods.

Answer 6

External Quality
Assessment Programs (EQAP); Proficiency Testing programs; EQAP; Proficiency testing programs; PT; long
