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 1996 MMQAP measurement comparability improvement studies: 1) Round Robin XXXVI Fat-Soluble Vitamins and Carotenoids in Human Serum, 2) Round Robin XXXVII Fat-Soluble Vitamins and Carotenoids in Human Serum, 3) Round Robin XXXVIII Fat-Soluble Vitamins and Carotenoids in Human Serum, and 4) Round Robin 9 Ascorbic Acid in Human Serum. The materials for Round Robin XXXVI were shipped to participants in January 1996; participants were requested to provide their measurement results by March 15, 1996. The materials for Round Robin XXXVII were shipped to participants in April 1996; participants were requested to provide their measurement results by June 14, 1996. The materials for Round Robin XXXVIII were shipped to participants in July 1996; participants were requested to provide their measurement results by September 20, 1996. The sample materials for Round Robin 9 were distributed in May 1996 with results due by July 2, 1996.
