A new survey of 21 Large Academic Medical Centers in the USA has revealed some sobering facts.  We assume that QC processes have evolved from the antique practices of the 1950s and 1960s, particularly since the introduction of "Westgard Rules" in 1981 and other evidence-based optimization techniques in subsequent decades. The reality appears to be the opposite. QC practices may be regressing, not evolving.

The continuing discussion of pre-analytical quality in the literature prompts us to update our review of current laboratory defect rates. From a laboratory in India, what can we see in recent developments in processes

In 2017, we conducted a QC Survey all over the world. But we primarily focused on the chemistry practices. What about hematology practices? We have just enough responses to help us paint a picture of the state of hematology QC.

In 2017, as part of the ESVCP meeting in London, we conducted and presented a small survey of veterinary laboratories and their QC practices. What do their results tell us about the state of quality control? Are they doing better QC than "human labs"?
