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, Spring and Fall 1997 MMQAP measurement comparability improvement studies: 1) Round Robin XXXIX Fat-Soluble Vitamins and Carotenoids in Human Serum, 2) Round Robin XL Fat-Soluble Vitamins and Carotenoids in Human Serum, 3) Round Robin XLI Fat-Soluble Vitamins and Carotenoids in Human Serum, and 4) Round Robin 10 Ascorbic Acid in Human Serum. The materials for Round Robin XXXIX were shipped to participants in January 1997; participants were requested to provide their measurement results by March 21, 1997. The materials for Round Robin XL were shipped to participants in April 1997; participants were requested to provide their measurement results by June 13, 1997. The materials for Round Robin XLI were shipped to participants in July 1997; participants were requested to provide their measurement results by September 19, 1997. The sample materials for Round Robin 10 were distributed in November 1996 with results due by January 15, 1997.
