My opinion is that there's not much difference between reversed and cured. If your pancreas can still pump out loads of insulin and you have gotten rid of your insulin resistance, then you no longer have type 2 diabetes, whether you call that cured or reversed or as I sometimes call it "post diabetic". If I went back to eating to the government dietary guideline of high carb low fat I'd probably become diabetic again, but currently I still consider myself cured, since I have blood glucose levels in the normal range and when I do have something starchy/carby/sugary, my blood glucose level will go up, peak, and come right back down. Although not a perfect analogy, I think of similar to if I fell out of a tree and broke my arm, had it set with a cast, it healed, the cast comes off and I'm cured of my broken arm. Yet, if I fell out of a tree again I could still end up with a broken arm again. So, maybe I just avoid falling from heights the rest of my life and I never get another broken arm. Same for my type 2 diabetes - maybe if I avoid doing what caused it in the first place then maybe it won't come back. Until it comes back, I say I'm cured. Time will tell.
If you had an OGTT as part of your diagnosis, it sure wouldn't hurt to ask for another one if your fasting blood glucose and HbA1c results are in the normal range (i.e. lower than "pre-diabetic".
You can also just do your own OGTT with some Lucozade and a blood glucose monitor.
Keep in mind that a low carb diet can skew the results a bit.
