Blood Tests and Insulin Injections
Question from Lees Summit, Missouri, USA:
Why is your blood sugar lower on one hand than the other when it is checked at the same time? What would cause a 10 mg/dl difference? What site is the most accurate for getting a true blood sugar?
Answer:
It is likely that it is not you, but that the meter isn’t any more accurate than that.
