Re: [IPk] For Melissa?

Hi Jane

The sensor is a sandwich of two electrodes with OXIDASE between them.
Oxidase reacts with the glucose and produce electricity. The ISIG is
the electricity that pass between the two electrodes.

When the sensor is new and Oxidase starts to react give hi ISIG that
falls to the normal during the two hours of preparation before the
first calibration. Every part of the body gives different ISIG level
and this is why we need to calibrate every new sensor.

During the time the Oxidase reacts with glucose and less oxidase
remain between electrodes to give proper ISIG. The ISIG fall a Little
bit every day of use. That's why you need calibration every 12 hours.

If you have low and stable blood sugars then the sensor last more. I
keep two sensors in a row for 15 days each. The last one where my
blood sugars was in mess lasts for 7 days only!

I hope that this information helps you
