2. Process Control: Qualitative and Semi-Quantitative QC-Module 8 2 Learning Objectives At the end of this module, participants should be able to:
Differentiate between built-in and traditional controls.
Describe how to use stock cultures for microbiology QC.
Discuss the use of quality control procedures for stains used in microscopic examination.
Describe methods for verifying performance of microbiological media.
3. Process Control: Qualitative and Semi-Quantitative QC-Module 8 3 Scenario Laboratory A performs a culture, and Pseudomonas aeruginosa is identified.
What QC measures can you use to confirm that the isolate is correctly identified?
4. Process Control: Qualitative and Semi-Quantitative QC-Module 8 4 The Quality Management System
5. Process Control: Qualitative and Semi-Quantitative QC-Module 8 5 Qualitative or semi-quantitative tests - Examples microscopic examinations
dipsticks
serologic procedures
microbiological procedures
any reaction that produces non-numeric results
6. Process Control: Qualitative and Semi-Quantitative QC-Module 8 6 Important Concepts sample management
staff competency
equipment maintenance
control materials
stains, media and reagents management
record keeping
7. Process Control: Qualitative and Semi-Quantitative QC-Module 8 7 Quality Control Materials built-in controls
control materials that mimic patient samples
reference organisms
8. Process Control: Qualitative and Semi-Quantitative QC-Module 8 8 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
9. Process Control: Qualitative and Semi-Quantitative QC-Module 8 9 Traditional Controls materials with known reactivity
mimic patient samples
assess the integrity of the entire test system
10. Process Control: Qualitative and Semi-Quantitative QC-Module 8 10 Using Traditional Controls test as per patient samples
use a positive and negative control
include a weak positive control for immunological procedures
choose positive controls close to the cut-off value
include control to monitor extraction phase
11. Process Control: Qualitative and Semi-Quantitative QC-Module 8 11 Stock Cultures for QC reference strains
in-house developed strains
predictable reactions in stains and media
ensure media, reagents and supplies work as intended
12. Process Control: Qualitative and Semi-Quantitative QC-Module 8 12 Sources for Obtaining Reference Strains ATCC-American Type Culture Collection
NTCC-National Type Culture Collection (UK)
CIP- Pasteur Institute Collection (France)
13. Process Control: Qualitative and Semi-Quantitative QC-Module 8 13 Stains are important— take care of them!
14. Process Control: Qualitative and Semi-Quantitative QC-Module 8 14 Stain Management use established procedure for preparation or reconstitution
label: content, concentration, date prepared and placed in service, expiration, initials
store appropriately
15. Process Control: Qualitative and Semi-Quantitative QC-Module 8 15 Quality Control for Stains As appropriate for particular stain:
check with known organisms or cells
examine for crystal shards or for precipitation
examine for contaminants such as bacteria and fungi
16. Process Control: Qualitative and Semi-Quantitative QC-Module 8 16 Gram Stain
17. Process Control: Qualitative and Semi-Quantitative QC-Module 8 17 QC of Microbiology Media verify performance of all media
in-house prepared: all batches
commercially prepared: new lot only
18. Process Control: Qualitative and Semi-Quantitative QC-Module 8 18 Media Problems to Avoid
19. Process Control: Qualitative and Semi-Quantitative QC-Module 8 19 Quality Control of Growth Media keep records for media prepared in-house
record outcomes in a dedicated media logbook for:
pH, sterility, ability to support growth using stock cultures, biochemical response of stock cultures
frequency
test each new batch or lot number
20. Process Control: Qualitative and Semi-Quantitative QC-Module 8 20 Summary qualitative tests produce non-numerical results
semi-quantitative tests give an estimate
establish a QC program for qualitative and semi-quantitative tests
21. Process Control: Qualitative and Semi-Quantitative QC-Module 8 21 Key Messages QC procedures followed by ALL staff
always record QC results and corrective actions
If QC results are not acceptable, do not report patient results!
