It involves pricking fingers and putting the blood on the glucose meter strip already inserted in the glucometer.

The glucometer gives fast, accurate reading within 15 to 20 seconds and is simple to operate.

Continuous Glucose Monitoring Device:

This device is placed under the skin and continuously measures sugar levels in body tissues.
