Like "That's pretty normal. Home meters are not accurate 100% so with your high blood sugar the results are within the standard accuracy range. It could also be many other things, something on your finger or the strip, temperature, rapidly changing blood sugar, etc. Your meter is approved for alternate site testing but you need to check to see how you need to set it before you test. You also need to bee aware that alternate sites do not give current blood sugar levels, they can be around 20 minutes behind your actual blood sugar. "
