Quality Control of Qualitative and Semi-Quantitative Procedures Flashcards
Quality Control Materials
◼ built-in controls
◼ control materials that mimic patient samples
◼ reference organisms
Built-in Controls
◼ integrated into the design of a test kit device
◼ automatically run with each test performed
◼ assess certain aspects of kit performance
◼ may not assess entire testing process
◼ materials with known reactivity
◼ mimic patient samples
◼ assess the integrity of the entire test system
Traditional Controls
◼ reference strains
◼ in house developed strains
◼ predictable reactions in stains and media
◼ ensure media, reagents and supplies work as intended
Stock Cultures
ATCC
American Type Culture Collection
NTCC
National Type Culture Collection (UK)
CIP
Pasteur Institute Collection (France)
◼ use established procedure for preparation or reconstitution
◼ label: content, concentration, date prepared and placed in service, expiration, initials
◼ store appropriately
Stain Management
Media Problems to Avoid
▪ out-dated
▪ dried-out
▪ contaminated
Human blood should be used
False
Quality Control of Growth Media
◼ keep records for media prepared in-house
◼ record outcomes in a dedicated media logbook
◼ frequency
If QC results are not acceptable, do not report patient results!
