Sigma Metric Analysis
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.
In a 2009 issue of Annals of Clinical Biochemistry, a study takes on two Point-of-Care HbA1c devices using two different reference methods. Both POC methods are standardized to the IFCC reference system and aligned to DCCT standards via the National Glycohemoglobin Standardization Program (NGSP). Both reference methods are also standardized against the IFCC reference method and traceable to DCCT and NGSP. If everything is standardized and traceable, there can't be any problems, right?
A poster at the 2009 AACC conference evaluated the performance of the new VITROS 5600 system. VITROS is well known for its MICROSLIDE and MICROTIP technologies. We review the data and generate graphic analysis.
