Terminology
“Quality Control” has always been a part of the clinical laboratory, but had been used exclusively for analytical activities. QC is designated to ensure the medical reliability of lab data.
We now know that we must analyze pre-analytical, analytical, and postanalytical activities and the terminology is NOW called “Performance Improvement” (PI)
Indicators/Monitors of Performance Improvement
Process Monitors Results are complied and evaluated routinely,
allows for identification of disruptions Outcome Monitors
Measurements as a result of processes Focus Monitors
Initiated in response to a suspected problem Benchmarking
Seeking an industry’s or profession’s best practices
Helps provide a starting point for improvement
Terminology
Quality Assurance (QA) is defined as taking measures to ensure high quality patient care. Involves monitoring all parts of a system and implementing changes when suboptimal performance is identified
Terminology (cont’d)

Terminology (cont’d)
Analytical StageSample testing
Postanalytical StageResult transcriptionResult deliveryResult reviewAction taken on basis of result
Quality Control Procedures
Daily temperature checks NIST (National Institute of Standards & Technology) Thermometer calibration (once when received from
manufacturer)
Equipment preventive maintenance program – includes routine maintenance such as oiling, cleaning, replacing filters, etc.
Quality Control Procedures (cont’d) All prepared media must be quality controlled
prior to use If media is purchased, can rely on manufacturer’s
QC, but lab must obtain a statement of quality control from manufacturer
All shipments should be inspected as it comes to lab
HOWEVER, chocolate and selective agars for Neisseria and Campylobacter MUST be rechecked by lab
Test media using ATCC strains Records maintained for 2 years Reagents should be QC’ed on each day of use,
new lot numbers, and/or with each test run
In-House Media QC log
Media Tracking Log
Quality Control Procedures (cont’d)
Antimicrobial Susceptibility QC Personnel Competency –
proficiency testing is one way this can be assured (CLIA requires this)
Continuing Education QC Manual – must be reviewed
and signed at least annually
