A physician calls and says that all the blood glucose results for his patients- from whom blood is drawn in his office and then sent to the laboratory – show low blood sugar/glucose. The physician states that there must be a problem with the laboratory instrument. What would you investigate to resolve the problem?

Measure insulin and glucagon levels in the blood. If blood glucose levels are too low, insulin levels will be too high and glucagon levels will be too low if nothing is wrong with the instrumentation used to measure glucose levels.
Just to add, I don't think anyone on this form know how specifically they measured blood glucose levels to know what's wrong with instrumentation.
