Evaluation of Inter-Arm Differences in Continuous Glucose Monitor Glucose Readings in Patients With Type 1 and Type 2 Diabetes
This is a clinical trial looking at differences in continuous glucose monitor (CGM) glucose readings between the left and right arms in adults with type 1 or type 2 diabetes. The study will enroll 60 participants who will wear a CGM sensor on both arms for 14 days.
Inclusion: Adults 18 years of age and over; Diagnosed with type 1 or 2 diabetes mellitus; Female participants with childbearing potential must have a negative urine pregnancy stick test, which has been confirmed by investigators; Willingness to wear a CGM on each arm for 2 weeks; A1c <7% within the past 6 months; Willing to attend 3 virtual call meetings over the course of the trial; Have active health insurance throughout the duration of the study; Willing to refrain from consuming or using commercial products containing ascorbic acid (vitamin C) or salicylic acid, and certain skincare products for the duration of the study due to their known potential to interfere with CGM readings (exposure via food is allowed); Participants must have a mobile phone that is connected to the internet and compatible with both "FreeStyle Libre 3" and "Libre by Abbott" apps.
Exclusion: Currently taking hydroxyurea; Blood transfusion within the previous 3 months; Any active dermatologic condition on the upper arms; History of or planned gastric bypass within the study period; Current systemic infections; History of allergic reactions or hypersensitivity to adhesives; Under the age of 18; Implanted medical devices (e.g., pacemaker, insulin pump); Use of any medical or other devices (e.g., TMS) incompatible with the FreeStyle Libre 3 Plus CGM; Critically ill or dialysis patients; Planned high-frequency electrical heat treatment (diathermy) during the study period; Subjects who are unable to fully understand the study or consent process will not be included in the study due to the lack of a qualified medical translator; Refusal to sign the informed consent document or HIPAA authorization form; Pregnant, planned pregnancy during study period, or currently breastfeeding.
