Would a blood glucose monitor with a low battery, but still working, give a false reading?

In brief: It Might

Like any other electronic device a good battery supply is essential if we want to get accurate readings.
Your numbers may be coming out accurate but change the battery to make sure. If you have already done that then your number should be accurate. I wouldn't place a whole lot of stock in blood sugars before you changed the battery as they may have been off. Start for now and you will be confident.
