Quality Requirements and Standards
The use of Quality Indicators (QI) is an important indicator that a laboratory has embraced and implemented a Quality Management System (QMS). But which Quality Indicators should a laboratory choose? And what does a particular QI tell us? As it turns out, some QIs are more important than others.
Here's a recent example proving the importance of the choice of quality requirement. A laboratory was reviewing the performance of a cholesterol method. By one local standard, the performance was not acceptable. By another standard (CLIA), it was. So is the method good or not? Which quality requirements are right? This case study looks at a number of quality requirements and compares them.
Molecular diagnostics is a field exploding with growth. Next Generation Sequencing (NGS), RNA and DNA microarrays, mass spectrophotometry are poised to enter the clinical laboratory. Special challenges arise when we try to apply "traditional" quality control and quality assurance models to these new testing technologies. Not only will we need to adapt current quality thinking to the practical realities of the new tests - we will definitely need to avoid repeating the mistakes we made in our traditional QC approaches.
I was privileged to participate in the Symposium “Top of Diabetes Diagnostics,” that was held in Zwolle, Holland, on September 2001. This special conference tackled not only harmonization, standardization, biologic variability, and tight glycemic control, it also covered the quality that HbA1c methods are currently achieving. Considering that diabetes is one of the major world health problems, the findings of this conference are particularly important
Traceability, Standardization, Harmonization Comparability. Even within the laboratory, these are not terms and concepts that excite most of us. But as the world gets smaller, as health records get more connected and as medical practices converge, reliable, comparable test results are going to matter more and more. Whether we want to get involved or not, we are already in the struggle for standardization.
