I just dug out the blood test that was done in 2000 to determine whether I was GAD positive. I was never given a clear yes or no. My endo (of the past 2 years) keeps saying, “I think you’re Type 2” because metformin reduces my insulin requirements. I was diagnosed at 32 y.o.
The test results are ICA Titer 1:4; ICA Result pos; GAD index -0.02; GAD result Neg; IA2 Index 0.009; IA2 Result Neg. At the time the test was done, I was told I was “on the cusp” of GAD positive.
I am a small person (120 lbs) who takes a total of 27 units a day of insulin (lantus and pre-meal R) plus 500 mg Metformin at bkfst and dinner.
I’d like to get more involved in research trials which often are looking for “Type 1”, but I’m not really sure what I am. Any insights would be much appreciated.
