I had the same problem as you - my first test cam back 9.4 but my second test after the diet was ok. I to was sick before the first test. I think i had the flu or a bug that was going around. try not to worry and follow the diet as this will affect the results if you dont. i missed my last meal and almost had to redo the test because of a high result (but still in normal range). good luck and let us know
