Sigma Metric Analysis
Another chance to get a second look at instrument performance. Over a year ago, we looked at cancer marker performance on the Vista. Now we examine a 2012 study that compared the method performance of the new Vista methods vs. the older Immulite methods. How do the two generations of Siemens instrumentation compare? Do those results match the other study?
As part of our continuing series of evaluations, we take a look at two point-of-care (POC) HbA1c analyzers. As standards on performance have tightened, have POC devices kept up? Has their improved performance matched the higher demands?
A chance to get a second look at instrument performance. In 2011, CCLM had a study of performance of the Menarini/ARKRAY ADAMS A1c HA-8180V analyzer. In 2012, Lab Med Online has another study, which gives us another opportunity to see if the first findings hold up.
A 2011 study performed analysis on the performance of cancer markers on the Siemens Vista. We use the data and calculate Sigma-metrics. How good do cancer marker assays need to be? Are new methods meeting those goals?
In a 2011 study, an India hospital laboratory undertook a quality assessment of their clinical chemistry methods using Sigma-metrics. Is laboratory method quality the same the world over?
