Hi doctor,

My doctor says that glucose reading given by home monitor is always 10% higher than the actual glucose reading from the laboratory test result. So, if my reading in the home monitor is 90 mg/dl, then my actual glucose is 81 (90 minus 9, 10% of 90). Is he right? Do you agree with this?

Hi,

Welcome to icliniq.com.

It is not like home glucose monitor will be 10% higher. It can be higher or the same or even lower than laboratory results.

In fact, in my observations, I have noticed it be slightly lower than the laboratory test result.

What I recommend is calibrate your home glucose monitor with the actual laboratory test report. I mean to say do the blood check immediately when the blood sample is being taken for laboratory test.
