Missing the targets
The biggest development in analytical performance specification (APS) is upon us. At the IFCC WorldLab meeting in Barcelona, the EFLM unveiled the next generation of biological variation specifications. Rigorously screened studies, through the use of the EuBIVAC checklist, now inform the setting of targets for analytical performance.
This is a major advance. It is a testament to the dedicated efforts of EFLM to produce the database after 5 years of hard work.
The next question to tackle: are these new goals so tight we can't hit them? Are some of our methods so bad they can't even meet the old goals? (See below, for examples...)
See the new EFLM database on biological variation
See a summary of APS derived from recent meta-analyses of biological variation studies.
An AU5800 in India
A recent study of an AU 5800 in a hospital in Hyderabad, India, raises questions about how instruments perform in a more challenging environment.
Are performance problems shown here from the lab, from the instrument, or from both?
ADVIA Centaur XPT Thyroid Testing in India
A recent study of an ADVIA Centaur XPT in a hospital in Hyderabad, India, raises questions about how instruments perform in a more challenging environment.
Are performance problems shown here from the lab, from the instrument, or from both?
TT4 Testing Performance Comparison
A recent study of the automated immunoassay methods compared the major diagnostic instruments against a ID-LCMS reference method.
When compared to the "true values", can any methods hit the most evidence-based (but old) biological variation-derived performance specifications?
Can any methods hit the minimum performance specifications, for that matter?
