Routine Validation and Reproducibility Testing of Laboratory Measures and Research Techniques Used for Metabolism Research (VAL)
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.
