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 2001 MMQAP measurement comparability improvement studies: 1) Round Robin XLIX Fat-Soluble Vitamins and Carotenoids in Human Serum and 2) Round Robin 14 Total Ascorbic Acid in Human Serum. The materials for both studies were shipped to participants in January 2001. Participants in Round Robin XLIX were requested to provide their measurement results by March 16, 2001. Participants in Round Robin 14 were requested to provide their measurement results by May 12, 2001.
