In your first thread I mentioned that the FDA set manufacturing guidelines for home glucose meters at ± [plus/minus] 20%. This means your 70
mg/
dl reading could be 70
mg/
dl or it could be as low as 56
mg/
dl or as high as 84 mg/dl. Home meters give an approximation not a true reading of glucose levels. Since your 100 mg/dl reading two minutes later falls out of this range, the questions remaining are:
1. How old is your father's meter?
2. Do the test strips have an expiration date?
3.
