Sigma Metric Analysis
In January 2011, the journal, Diabetes Care, published a study of blood glucose meters: Suboptimal Performance of Blood Glucose Meters in an Antenatal Diabetes Clinic. In addition to highlighting some of the findings, we add Sigma-metrics calculations and Method Decision charts.
An abstract from the 2010 AACC/ASCLS meeting compared Three POC Analyzers for HbA1c. Given the recent study from Lenters-Westra and Slingerland (where 6 out of 8 analyzers couldn't meet the standards for analytical performance), how do these three devices fare?
A recent evaluation in CCLM of the Menarini/ARKRAY ADAMS A1c HA-8180V analyzer gives us another opportunity to see if current performance on the market can meet the tightening requirements for HbA1c.
In a 2008 issue of Annals of Clinical Biochemistry, a study looked a seven different 25-hydroxyvitamin D methods, compared with liquid chromatography-tandem mass spectometry. Using quality requirements developed by and derived from Stockl, Sluss, and Thienpont, we examine this methods with Sigma-metric analysis.
