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 2014 MMQAP measurement comparability improvement studies: 1) Round Robin LXXV Fat-Soluble Vitamins and Carotenoids in Human Serum and 2) Round Robin 40 Total Ascorbic Acid in Human Serum. The materials for both studies were shipped to participants in January 2014. To help reduce overhead costs and avoid raising participation fees, the materials for Round Robin LXXVI Fat-Soluble Vitamins and Carotenoids in Human Serum and Round Robin 41 Total Ascorbic Acid in Human Serum were also shipped in the same shipping container. Participants in Round Robins LXXV and 41 were requested to provide measurement results by April 18, 2014.
