|Title:||NIST Micronutrients Measurement Quality Assurance Program Winter 2009 Comparability Studies: Results for Round Robin LXV Fat-Soluble Vitamins and Carotenoids in Human Serum and Round Robin 30 Ascorbic Acid in Human Serum|
|Published:||August 05, 2013|
|Abstract:||The National Institute of Standards and Technology coordinates the Micronutrients Measurement Quality Assurance Program (MMQAP) for laboratories that measure fat- and water-soluble vitamins and carotenoids in human serum and plasma. This report describes the design of and results for the Winter 2009 MMQAP measurement comparability improvement studies: 1) Round Robin LXVI Fat-Soluble Vitamins and Carotenoids in Human Serum and 2) Round Robin 30 Total Ascorbic Acid in Human Serum. The materials for both studies were shipped to participants in December 2008; participants were requested to provide their measurement results by March 31, 2009.|
