To Evaluate the Efficacy and Safety of Multi-parameter Non-Invasive Glucose Sensors for for Blood Glucose Measurement
Study Details
Study Description
Brief Summary
This was a prospective, multicenter, open-label, self-controlled study to evaluate the efficacy and safety of multi-parameter non-invasive glucose meters for blood glucose measurement,planned enrollment of 200 patients with type 1 or type 2 diabetes.
Comparing glucose measurements from the Non-Invasive Glucose monitoring system to venous blood glucose or fingertip blood glucose to evaluate System accuracy capability.

Detailed Description
At the same time, blood glucose was measured by non-invasive blood glucose meter, Accu-Chek Guide blood glucose meter and EKF Biosen C-Line. Eight groups of blood glucose values were collected from each subject during fasting, after breakfast and after lunch.After the end of blood glucose measurement, the data were recorded, including adverse events and device defects during the test. The subjects were required to stay in the examination room for 5-10 minutes, during which they completed the product use evaluation questionnaire.
Study Design
Arms and Interventions
Arm | Intervention/Treatment |
---|---|
Experimental: Non-invasive glucose meter The noninvasive glucose meter was entrained on the finger, Glucose concentration levels were measured by measuring physiological parameters related to metabolic heat and local oxygen supply. |
Device: Non-invasive glucose meter
Blood glucose levels were measured while fasting, after breakfast, and after lunch,Place your index finger into the non-invasive blood glucose meter and wait for the instrument to display the reading.
|
Active Comparator: Accu-Chek Guide blood glucose meter Being used for quantitative determination of blood glucose concentration in fresh capillary whole blood taken from fingers. |
Device: Accu-Chek Guide
Blood glucose levels were measured while fasting, after breakfast, and after lunch,Use Accu-Chek Guide blood glucose meter to prick the finger and obtain blood for glucose measurement
|
Active Comparator: EKF Biosen C-Line Using the hexosyl enzymatic method to detect plasma glucose values |
Device: EKF analyzer
Blood glucose levels were measured while fasting, after breakfast, and after lunch,After collecting venous blood and separating plasma, blood glucose detection is performed using the EKF analyzer with the hexokinase method.

Outcome Measures
Primary Outcome Measures
- The results were analyzed by consensus error grid (CEG) [After 2 days of blood glucose measurements]
The proportion of the results lie within zone A and zone B of the consensus error grid (CEG)
Secondary Outcome Measures
- Mean Absolute Relative Difference (MARD) [The day after the blood glucose measurement]
It is calculated by taking the absolute difference between the two values, dividing it by their average. A smaller MARD value indicates a smaller relative difference between the two values, indicating higher consistency between them.
- The 20/20% agreement rates [The day after the blood glucose measurement]
the proportion of Non-invasive blood glucose values that were within 20% of paired reference blood glucose values >80 or 20 mg/dL of reference blood glucose values ≤100 mg/dL
- Accessibility evaluation Questionnaire for non-invasive glucose meter [The day after the blood glucose measurement]
The questionnaire covers the subjects' self-monitoring of blood glucose status, their awareness and expectations of non-invasive testing, as well as their subjective feelings after using a non-invasive blood glucose meter.
