Hello everyone,I have a question.I just checked my mail box and I got the lab papers for my sons blood work but,I also have a prescription for them to have a bone age film done of their hands and wrists.I never had this done before.what would be the reason for this?I had some concerns about my 7 year old height.Would this be the reason? I couldn't wait until monday to call our nurse.I was hoping someone knew about this. Thanks for any answers.
