Overview
Brief Summary
The purpose of the research is to determine whether a noninvasive hearing test may be used to predict blood glucose in people with diabetes.
Detailed Description
Participation in the study will involve listening to sounds through earphones while blood glucose levels are measured by taking blood samples using a lancet. During the study, blood glucose levels will be increased by drinking a beverage containing sugar. Up to five visits to the NCRAR will be needed over a six-month period to complete the study. Each visit lasts either two or four hours, and will be scheduled at your convenience. You will be paid $20 for the first 2-hour screening visit and $50 for each 4-hour visit. You will be paid $30 if you are selected to participate in a 2-hour Attention Correlation Test that a sub-set of 10 participants will complete.
