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 Summer 2014 MMQAP measurement comparability improvement studies: 1) Round Robin LXXVI Fat-Soluble Vitamins and Carotenoids in Human Serum and 2) Round Robin 41 Total Ascorbic Acid in Human Serum. To avoid increasing participation fees, the overhead costs for these programs were minimized by shipping the materials in January 2014 together with the samples for FSV Round Robin LXXV and VC Round Robin 40. Participants were requested not to analyze any of the Summer samples before June 1, 2014 but to provide their measurement results by September 15, 2014. Participants were reminded of the due-date by e-mail on August 4, 2014.
