Just got faxed a friend's horse's blood test results.  I told her she needed to do ACTH, Insulin, Glucose and Leptin.  The ACTH came back at 241 pg/mL, but the Leptin came back at <1 ng/mL and Glucose was done at the vet's clinic and it came back as <10 mg/dL and their range is 60-125 mg/dL.  As far as I know no insulin was done so I asked her to ask the vet.  These tests were done at Cornell.  We know this horse is Cushings but he is a thoroughbred so could these low results be correct?
