Trial Outcomes & Findings for Association of Amino Acid Prevalence and Chronic Brain Injury (NCT NCT02113124)

NCT ID: NCT02113124

Last Updated: 2015-12-15

Results Overview

5 ml of blood will be acquired following a 8-hour fasting period to determine baseline concentrations of amino acids. A meal will then be provided and another blood sample will be acquired 90 minutes after completing the meal to examine the change in amino acid concentration. These samples will be used to determine the levels of each essential amino acid present.

Recruitment status

COMPLETED

Target enrollment
