Question
My 66 year old wife, who has
type 2 diabetes,
recently joined a
new insurance plan
and was required to use a new blood glucose meter. She noticed that the readings
seemed very high, so she
has started to test at the same time with
the old meter, and the readings differ by 7-22 mg/dL [0.4-1.8 mmol/L]. Is
this common? Perhaps this particular machine is defective?
Answer
I doubt that the meter is defective, but it's possible. Blood glucose meters are designed to read within 10-15% of lab values. So, you can judge by what your
wife's level was at the time on the other meter.
You can test both meters for accuracy by
using the control solution that came with them. If the values
are within the established range, the meter is
operating properly. If not, call the manufacturer, and I'm sure they will replace it.
