I'm a bit confused by the question- do you think doctors have targets they have to meet?
I don't think a doctor would tell someone they were diabetic unless that's what the tests show. In fact from various threads here the problem seems the reverse that people aren't alerted early enough.
I'm wondering whether you were diagnosed as a diabetic? If you were and have been careful with your diet it may be that the next test showed you in non-diabetic ranges but that doesn't void the first test. In my (admittedly new experienced) views even if your tests do come down if you fail to eat appropriately you will end up in the diabetic range.
