What is QMS
Quality managment system
Coordinated activities to direct and control an organisation with regard to quality
What is quality?
Accuracy, reliability and timeliness’s of reported test results
What can ineffective managment of quality lead to?..
Misdiagnosis of patients
Delay in treatment of patients
Incorrect treatment given to patients
Additional testing
QMS vs QA vs QC
QMS is the overall system, QA is the part of the system that makes sure all requirements are met and QC is fulfilling the quality requirements
Quality roles within the lab
Lab director
Quality manager
Departmental quality officer
Section leads
Everyone
3 phases from sample collection to result interpretation
Pre analytical - samples collection, transport and receipt in the lab
Examination - producing the result
Post examination - reporting the result
Standards for laboratories
ISO 15189:2022
Labs if they meet this standard can become UKAS accredited
What does UKAS stand for?
United Kingdom accreditation service
What legal requirements are there for blood banks and NI blood transfusion services? Who is the regulatory body for inspecting blood banks?
Blood safety and quality regulation 2005
MHRA

What is acceptable IQC?
A target mean is established for every analyse on the relevant IQC material
A result must be within 2SD of target mean to be acceptable
IQC can identify bias or imprecision
Levy Jennings chart
Looks at target mean and individual IQC results. Compares each result to the target mean and how many SD the IQC results lie in
Accuracy vs precision
Accuracy is the ability to produce results that reflect the true value. Precision relates to the ability to reproduce results.
Potential causes of imprecision
Mechanical issue - inconsistent aspiration of reagents or sample. May be due to a damaged sample or reagent probe
Bubbles in reagent
Could be an issue with the IQC material itself - improper mixing or short sampling
How does EQA work?
Labs register for EQA schemes for their tests. Lab samples are processed.
Compared to a reference value and other labs using stage same methods as this lab. Performance can be assessed over time.
Retrospective
Analytical variation - what is it?
Taken from an EQA report.
Shows the variation that can exist when the same sample is analysed for the same test but on different instruments, different laboratories and using different methods.
Post examination processes
Procedures in place for the release of results
Procedures in place for the storage, retention and disposal of clinical samples
Pre examination process
Sample and request form documents
Transport
What is an audit?
A systematic, independent and documented process for obtaining evidence and
evaluating objectively the extent to which audit criteria are fulfilled.
Why are audits good?
Great way of confirming that we are doing what we say we do.
Compares practice to pre defined criteria eg SOPs
Help to identify errors or deficiencies in systems
Potential for improvement
