My fiancée will be moving to the UK from the US at the end of the year. She has a medical disorder, which took a long time to diagnose, for which she is now receiving treatment. This involves taking medication and regular visits to a specialist. All of this treatment is available on the NHS.
I'm hoping you can tell what is the most efficient way to transfer her treatment to the UK, so that she can be seen under the NHS when she is here? In particular, she is anxious to avoid having to go through all of the tests again and to have to be rediagnosed, which I assume would be the default position if she were just to show up at a GP.
