Repeated blood glucose measures using a novel portable glucose meter

Area of Science:

• Preclinical research
• Animal models
• Diabetes research

Background:

• Accurate blood glucose monitoring is crucial for preclinical diabetes research.
• Existing methods for mouse blood glucose measurement can be time-consuming or invasive.
• Adapting human physiological tests to animal models requires reliable monitoring tools.

Purpose of the Study:

• To evaluate a novel portable blood glucose meter for repetitive and rapid glucose measurements in mice.
• To validate the meter's performance against a conventional glucose analyzer.
• To assess the feasibility of using this device for a mouse insulin tolerance test (ITT).

Main Methods:

• A novel portable blood glucose meter was used for serial blood glucose measurements in mice.
• Comparative analysis was performed against a standard automated glucose analyzer.
• Measurements were taken from capillary and trunk whole blood.
• The mouse insulin tolerance test (ITT) protocol involved repeated sampling post-insulin injection.

Main Results:

• The portable meter demonstrated high correlation with the conventional analyzer for both capillary and trunk blood.
• Measurement variability over five consecutive determinations was approximately 3%.
• Repetitive measurements could be obtained at intervals of about 70 seconds.

Conclusions:

• The novel portable blood glucose meter is precise and reliable for measuring mouse blood glucose.
• This device facilitates rapid, repetitive sampling, making it suitable for tests like the mouse ITT.
• The meter offers a valuable tool for advancing preclinical diabetes research in rodent models.
