Yes, rising ACTH can cause rising Insulin levels which of course can lead to laminitis. I had to learn that it just makes sense to test Insulin, ACTH and Glucose every time. I think that some vets may not know that Insulin levels can rise during the seasonal rise of ACTH.
Mara, do you have the barn hay analyzed? I know this can be hard at many boarding stables because they get multiple loads of hay during a given year.
