Cmate Blood Glucose Analyzer: Clinical Comparison Study of Fasting Blood Glucose Levels in the Morning

Cmate Blood Glucose Analyzer: Clinical Comparison Study of Fasting Blood Glucose Levels in the Morning

As of February 2024, there are 529 million people worldwide living with diabetes. The number of diabetes patients continues to rise annually, and there is also a trend toward younger patients. Blood glucose management is crucial for prediabetes and diabetes patients. Effectively controlling blood glucose levels can reduce the risk of complications such as vascular complications, retinopathy, cardiovascular disease, and kidney disease. Traditionally, blood glucose monitoring in home settings has primarily relied on fingerstick whole blood samples combined with a blood glucose meter. However, this method poses risks associated with the disposal of used lancets and test strips, and the discomfort caused by the blood draw process can also lead to psychological stress for users. To enhance users' willingness to monitor blood glucose regularly and reduce environmental pollution from waste, the non-invasive blood glucose measurement system applied in this study is a non-invasive monitoring technology that is not a medical device and has not yet been marketed. It is currently undergoing the application process for FDA medical device certification in the United States. This trial will collect fasting venous plasma glucose levels, HbA1c, fingerstick whole blood glucose levels, and non-invasive glucose levels from patients in the morning. The primary analysis indicator is the correlation analysis between venous plasma glucose levels and non-invasive glucose levels.
