I have a 12 year old who just got diagnosed with Cushings. You need to get to an endocrinolgist - dosn't have to be pediatric as I went to a regular one who does do kids but dosen't specialize in it. The wait was too long for the peds one. She needs to have a 24 hour urine test - my daughters blood test was normal but the urine was off the charts! Only Endocrinologists know what tests and how to read them. YOu can find out more info on the test from the website.
