Get another Doctor that is not SO gullible that he looks at blood tests reuskts and SEES they are elevated and then believes an Endo that has NEVER seen your child...and start all over if you have to.  I know it’s a pain but you will not ret until you do it...When she is diagnosed, sue the Doctor who is messing you around.  :)   (Get a bone age to confirm that her bone age is advanced which it will be if this is NOT early puberty.) Geez these people wind me up no end...
