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 1999 MMQAP measurement comparability improvement studies: 1) Round Robin XLV Fat-Soluble Vitamins and Carotenoids in Human Serum, 2) Round Robin XLVI Fat-Soluble Vitamins and Carotenoids in Human Serum, and Round Robin 12 Vitamin C in Human Serum. The materials for Round Robin XLV were shipped to participants in January 1999; participants were requested to provide their measurement results by April 2, 1999. The materials for Round Robin XLVI were shipped to participants in June 1999; participants were requested to provide their measurement results by September 10, 1999. The sample materials for Round Robin 12 were distributed in February 1999 with results due by March 26, 1999; a "Final Report" that combined results for Round Robins 11 and 12 was distributed in August 1999.Citation
