Noninvasive Blood Glucose Monitoring Using Otoacoustic Emissions
- Conditions
- Diabetes
- Registration Number
- NCT01073137
- Lead Sponsor
- Portland VA Medical Center
- 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.
