We take a look at data on a new mid-volume chemistry analyzer, based on data from an abstract at the 2009 AACC/ASCLS/CSCC meeting. If you buy the latest generation of chemistry instruments, does that guarantee you're getting world class methods?

We recently received a set of data for a chemistry analyzer. An analysis of these numbers gives us an eye-opening glimpse of real-world performance. On some tests, there were Sigma-metrics higher than 20! And yet on one test, the Sigma metric was actually below 1.0!! See which tests were good, which ones were great, and which ones were just plain ugly.

Now that we know how to translate the manufacturer's performance claims into Six Sigma metrics, let's take a hard look at some real-world data. With a performance study supplied by a "near-patient" chemistry anlayzer, we find out just how good (and how bad) performance of tests are when they're at the POC.

Continuing in our series on translating method validation studies into Six Sigma metrics, we examine a Roche Integra 400+ chemistry analyzer, with data provided by St. Joseph Hospital in Houston, Texas. The results are stunning.

Working with CAP Today's recent survey of High Volume Hematology Analyzers, we convert the manufacturer precision claims into Six Sigma estimates. Want to see how the instruments shape up?
