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 1994 MMQAP measurement comparability improvement studies: 1) Round Robin XXX Fat-Soluble Vitamins and Carotenoids in Human Serum, 2) Round Robin XXXI Fat-Soluble Vitamins and Carotenoids in Human Serum, 3) Round Robin XXXII Fat-Soluble Vitamins and Carotenoids in Human Serum, 4) Round Robin 5 Ascorbic Acid in Human Serum, and 5) Round Robin 6 Ascorbic Acid in Human Serum. The materials for Round Robin XXX were shipped to participants in January 1994; participants were requested to provide their measurement results by March 19, 1994. The materials for Round Robin XXXI were shipped to participants in April 1994; participants were requested to provide their measurement results by July 25, 1994. The materials for Round Robin XXXII were shipped to participants in July 1994; participants were requested to provide their measurement results by August 30, 1994. The sample materials for Round Robin 5 were distributed in April 1994 with results due by May 31, 1994. The sample materials for Round Robin 6 were distributed in August 1994 with results due by September 30, 1994.
