Effectiveness and Safety of the RIGHTEST™ CGM System for Blood Glucose Management in Persons With Diabetes Mellitus

Brief Summary

The trial is expected to enroll 50 confirmed cases of type 1 or type 2 diabetes. All eligible subjects must wear a continuous glucose monitoring system on both the left and right upper arms for a maximum of 15 days (360 hours) and adhere to the clinical visit protocol. After enrollment, all subjects will be randomly assigned to either Group A or Group B to determine the time points for clinical visits. All subjects will have venous blood drawn on days 1, days 5 (±1), 10 (±1), and 15 (-1) post-wearing. All subjects will remove all devices on day 15 (-1) based on system prompts and undergo a telephone follow-up on day 4 (±3) thereafter. This clinical trial does not involve long-term follow-up. During the trial, the blood glucose values measured by the "continuous glucose monitoring system" worn by the subjects will be analyzed against the YSI venous blood glucose values measured at the medical institution on days 1, 5 (±1), 10 (±1), and 15 (-1) as control reference values. This analysis aims to evaluate the accuracy, repeatability, stability, high and low blood glucose event alerts, and safety of the continuous glucose monitoring system. Additionally, fingertip blood glucose measurements taken by subjects during home use will be collected to assess the operational feasibility of the continuous glucose monitoring system in a home setting.
