NIST Micronutrients Measurement Quality Assurance Program Summer 2002 Comparability Studies. Results for Round Robin LII Fat-Soluble Vitamins and Carotenoids in Human Serum and Round Robin 17 Ascorbic Acid in Human Serum.

摘要

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 Summer 2002 MMQAP measurement comparability improvement studies: (1) Round Robin LII Fat-Soluble Vitamins and Carotenoids in Human Serum and (2) Round Robin 17 Total Ascorbic Acid in Human Serum. The materials for both studies were shipped to participants in June 2002; participants were requested to provide their measurement results by September 13, 2002.
