My 4 1/2 yr old went to the endo the other day and we are going to do a different test that she says will give us a different outlook on his growth. We did the bone age when he turned 4 and for the first time, he was below his calendar age. It was 3 1/2...which she was fine with and most folks around her seem fine with also. At any rate she said it would measure if he is getting too much of the steroid. I believe she called it an IGH or something GH. That makes me think growth hormone. Anyway...this is a first for us and I wondered if any of you have had any experience with this test. If you look at the charts....Kyle is nearing the 0% for his height and this really troubles me.
