Hello kmsmom! I hope you do get some answers soon. Not every state performs the NPD and I heard that it is uncomfortable for children.
How is your daughter's weight and did she have a fecal fat test/elastase done?
Steve at ambrygen.com is very helpful and could answer some questions for you. He is usually very good with answering you back.
Good luck and hugs!
