@Rachox - Do you actually know of anyone who has actually lost their annual A1c and retinopathy screening as a result of coming off the register?
Please don't think I'm being confrontational, I'm not, but I read lots anecdotally of people losing thise services, but I can't think of one personal I have personally seen say it has actually happened to them, as opposed to fearing it will appen.
Having been off the register quite some time, I still have an annual A1c and rretinopaathy screening. In fact, my agreeing to the annual A1c was something my GP was extremely keen on.
