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 1995 MMQAP measurement comparability improvement studies: 1) Round Robin XXXIII Fat-Soluble Vitamins and Carotenoids in Human Serum, 2) Round Robin XXXIV Fat-Soluble Vitamins and Carotenoids in Human Serum, 3) Round Robin XXXV Fat-Soluble Vitamins and Carotenoids in Human Serum, 4) Round Robin 7 Ascorbic Acid in Human Serum, and 5) Round Robin 8 Ascorbic Acid in Human Serum. The materials for Round Robin XXXIII were shipped to participants in January 1995; participants were requested to provide their measurement results by March 20, 1995. The materials for Round Robin XXXIV were shipped to participants in April 1995; participants were requested to provide their measurement results by July 24, 1995. The materials for Round Robin XXXV were shipped to participants in July 1995; participants were requested to provide their measurement results by September 15, 1995. The sample materials for Round Robin 7 were distributed in January 1995 with results due by late May 1995. The sample materials for Round Robin 8 were distributed in October 1995 with results due by December 18, 1995.
