|Title:||NIST Micronutrients Measurement Quality Assurance Program Winter and Summer 2000 Comparability Studies: Results for Round Robins XLVII and XLVIII Fat-Soluble Vitamins and Carotenoids in Human Serum and Round Robin 13 Ascorbic Acid in Human Serum|
|Published:||August 07, 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 and Summer 2000 MMQAP measurement comparability improvement studies: 1) Round Robin XLVII Fat-Soluble Vitamins and Carotenoids in Human Serum, 2) Round Robin XLVIII Fat-Soluble Vitamins and Carotenoids in Human Serum and 3) Round Robin 13 Total Ascorbic Acid in Human Serum. The materials for Round Robin XLVII were shipped to participants in February 2000; participants were requested to provide their measurement results by May 12, 2000. The materials for Round Robin XLIII and Round Robin 13 were shipped to participants in June 2000; participants were requested to provide their measurement results by September 15, 2000.|
