All of the above
 
A Quality Assurance program is defined as:
Comparison testing between your in-clinic laboratory and a reference laboratory
A program of defined procedures designed to create confidence in laboratory results
Specific procedure and tasks designed to detect and minimise analytical errors
Electronic checks performed by the instrument
All of the above
 
A Quality Control program is defined as:
Specific procedures and tasks designed to detect and minimise analytical errors
Comparison testing between your laboratory and a reference laboratory
Electronic checks performed by the instrument
Monitoring of performance relative to a peer group
All of the above
 
How frequently should quality control materials (QCM) be run?
Once a month
As per manufacturer recommendations
Once a week
Ideally every day before a patient sample is run
Only when the instrument is not functioning correctly
 
Which of the following is NOT a pre-analytical source of error?
Post-prandial lipaemia
EDTA contamination of a serum sample
Inadequate mixing of a specimen
Inappropriate sample storage
Incorrect transcription of a result into the patient file
 
Regarding Total Analytical Error, which of the following is false?
It includes instrument imprecision
It includes instrument bias
It should only be assessed at the time of instrument set up
It should be compared against published values for Total Analytical Error Allowable
It is the basis for determination of appropriate QC control rules
 
After running quality control material (QCM) and finding that the result is unacceptable, what is the appropriate course of action?
Rerun the QCM repeatedly until the result is acceptable → run patient samples
Do not run patient samples → call the instrument manufacturer
Troubleshoot → rerun QCM → if acceptable, analyse patient samples
Send the QCM to a reference laboratory to analyse
Troubleshoot → analyse patient samples
 
Which of the following forms part of non-statistical QA for haematology POCT?
Blood film assessment
Review of instrument cytograms
Assessment of packed cell volume (PCV)
Checking that the HCT (%) is 1/3 of the haemoglobin concentration (g/L)
All of the above
 
Which type of chart is recommended for monitoring external QC results?
Bland-Altman
Levey-Jennings
Passing-Bablok
Scatterplot
ROC curve
 
A control rule for error detection should detect errors with a probability of error detection and probability of false rejection of:
>85% and <5%
>80% and <5%
>80% and <10%
>85% and <10%
>75% and <5%
