Appointment with Genetic Doctor

I have to take Chloe to the genetic doctor tomorrow and the G.I. doctor that she saw Friday sent me instructions for them to go ahead and test Chloe for Hirschsprung's Disease. I am asking everyone to pray for her that she doesn't have the disease and that if that's not the problem that the doctors will find out what's causing her to stay constipated. They are also testing her to see if she has any kind of genetic disorders that are causing all her problems and mainly her malformed ears and hearing loss. Thank you.
