Standarization or Standarisation? Harmonization or Harmonisation? We seem to be headed toward a schism in performance specifications, rather than a consensus. Here's a current comparison of Global Performance Specifications for Chemistry Assays.
Westgard QC is proud to announce the publication of the 2023-2024 edition of Dr. Sharon S. Ehrmeyer's book, The Poor Lab's Guide to the Regulations.
Determining your QC frequency used to be the reserve of the few and highly sophisticated. It's time we made some calculators available so the rest of the world can do it.
We've talked about Westgard Rules for decades, and we've talked about Six Sigma for years. So what happens when we try to talk about both at the same time? Westgard Sigma Rules
CCLM has published a set of 13 analytical performance specifications for measurement uncertainty. Only 7 years after the Milan Consensus Meeting. And only 15-20 years after MU took center stage in the laboratory quality debate.
The results are in! More than 600 laboratories from more than 100 countries around the globe answered the 2021 Westgard survey on QC practices. How are labs really performing quality control? The answers may surprise you.
Uncertainty in How to Calculate Measurement Uncertainty: Different approaches for incorporating effects of clinically significant bias
Funny thing about measurement uncertainty - it's not always clear how to calculate it. Particularly when clinically significant bias exists.
