s husband did a comparison test and his number was normal at 86 would seem to indicate that the machine is NOT giving false

blood sugar probably really IS that high, and this is extremely dangerous -- could
be life-threatening. It really is imperative that she have a true lab test done to see if there really is a blood sugar problem. She could do a glucose test in the lab to compare the number with the number that the lab gets if she thinks that her machine is in error.
