Study IDST000136
Study TitleNIST lipidomics intralaboratory study
Study TypeDiet comparison
Study SummaryTargeted lipids were quantified and compared to the quantities of other labs across the nation. Comparisons were between pooled serum from humans who have consumed flax seed for the past month, pooled serums from humans who have consumed fish oil for the last month, and pooled serum from humans who have not consumed either flax seed or fish oil for the past month. Pooled samples were prepared in triplicate.

Project DOI:doi: 10.21228/M8XW20
Project Title:NIST lipidomics intralaboratory study
Project Type:Lipidomics, targeted
Project Summary:Relative quantities of lipids were compared between three different human serum sample sets and compared to the results of other laboratories. Human serum samples were pooled from people who had either ingested fish oil supplements, flax seed, or neither for the last month. NIST SRM 1950 human pooled blood plasma was used for quality control and method development. Inidvidual lipids among several classes were targeted, including phosphoglycerolipids, triacylglycerides, diacylglycerides, sphingolipids, cholesterol and cholesteryl esters.
