Because I have type 2 diabetes as well as CKD, I would think you should see an endocrinologist first because you may have pre-diabetes. Your value of 6.4 is higher than normal which may lead to CKD. @gingerw is correct in that the trend is most important for kidney function and diabetes control. The unfortunate part for me is seeing a kidney doc regularly because they are so booked for stages 4 & 5, and end stage kidney disease. I have found that many nephrologists prefer 6 month follow ups for stage 3 or earlier. Stage 3 is quite vulnerable because in my opinion it requires 3 month visits. For CKD patients, control in many cases are diet, water intake and exercise. There is so much more and this forum has much help from others in making good choices on what to eat especially like @kamama94.
