Abstract

The National Institute of Standards and Technology coordinates the Micronutrients Measurement Quality Assurance Program (MMQAP) for laboratories that measure fat-soluble vitamins and carotenoids in human serum and plasma. This report describes the design of and results for the Winter, Spring and Fall 1988 MMQAP measurement comparability improvement studies: 1) Round Robin XII Fat-Soluble Vitamins and Carotenoids in Human Serum, 2) Round Robin XIII Fat-Soluble Vitamins and Carotenoids in Human Serum, and 3) Round Robin XIV Fat-Soluble Vitamins and Carotenoids in Human Serum. The materials for Round Robin XII were shipped to participants in January 1988; participants were requested to provide their measurement results by March 2, 1988. The materials for Round Robin XIII were shipped to participants in May 1988; participants were requested to provide their measurement results by July 1, 1988. The materials for Round Robin XIV were shipped to participants in August 1988; participants were requested to provide their measurement results by October 1, 1988.
