###Human: Is it true that home glucose monitor always shows 10% higher value of the actual lab result? ###Assistant: Hi. 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.
