Summary

The purpose of this research study is to validate (check the accuracy of) laboratory assays, intravenous catheter insertion, and equipment or devices and their reproducibility, which is necessary to perform high quality research on chronic diseases (obesity, pre-diabetes and type-2 diabetes, dyslipidemia, non-alcoholic fatty liver disease, cardiovascular disease, etc.), nutrition, and metabolism (the process by which a substance is handled in your body) at the University of Missouri. As technology changes and we start to use new testing methods, it is necessary to compare results from old tests, equipment and devices and new tests, equipment, or devices and the reproducibility of these measurements to make sure we are getting accurate results. Reproducibility means performing the same test more than once to see if the same results can be achieved each time.

Type	Name	Description
OTHER	endothelial cell collection	Participants may opt to have testing performed including blood sampling, intravenous catheter placement with endothelial cell collection, oral glucose tolerance test, consuming a test meal, having imaging performed such as MRI, DEXA, MRS to investigate use of different assays, different sample treatment approaches to determine optimal conditions that produce the most accurate and reproducible results, and/or repeat testing on different days or with different equipment that measures the same variable.
