From what I've read a GAD positive test is positive, the numbers don't mean anything. I've had 3 GAD tests, first one 519, 2nd around 80 and the 3rd over 100. I have relatively normal blood sugars (a bit of insulin resistance). Neither past or current endo's can tell if I have/will develop LADA. GP says if I was going to get it I would have it by now. Consensus on this forum is that I have a very slow developing LADA in long honeymoon period. C peptide just below middle of range. So I am keeping an eye on my sugars so if anything happens I can catch it early
