Elaine, I replied to the email you sent me, I know people have been able to do both the test and get the RDZ in the UK so I hope your vets are able to provide that for you if your cat tests positive.

You could also check out the Yahoo FelineIBD forum, there are UK members on there and they will hopefully be able to advise you on non prescription foods that will help while you have your vet get the testing information for you.
