Just went and looked at my sons book and he had at the time of testing 25% hearing capacity in one ear and 5% in the other but he now has 87% and 92% which is fantastic for me..
He actually has to go back in a months timee for a re-screen

I really hope your dd is just taking her tim eand its nothing major its a very hard path if anything is found and very gruelling my son disliked it and as soon as he would notice the dr's door he would scream cause he knew exactly what he was in for..
