I tried to make it a ‘wherever’ statement and stress the lack of info on the type of test carried out.
I think there’s a, imo, justifiable, scepticism around high street testing. Yes there are likely to be a number of trained, knowledgeable people doing it and as long as the tests have been through a formal, peer reviewed, series of blind tests etc and their effectiveness matches those done in a more clinical environment then there’s no problem. If it’s just ‘give us a drop of blood and we’ll tell you you’re allergic to peas and beetroot’ then I think people need to be cautious.
It’s about the consequences, should people be cutting out whole food groups etc based on a test they have no real knowledge about? If people are informed and understand what is being done, why and are given suitable follow up care and advice (perhaps including a referral for more, errm, formal/traditional testing) then fair enough.
My wife was ‘diagnosed’ as a coeliac by an alternative practitioner. We had huge dietary change, other expensive treatment etc and symptoms persisted. When she left a stressful job sometime later all of the symptoms disappeared. I guess it’s left me more questioning of alternate medicines as a result.
