I am thinking of ordering some blood tests for myself to check a few things with my health. My issue is that if anything flags up I will then have to go to my GP and tell them my concerns and why and I expect that the GP will annoyed that I have been doing these tests? I understand they will would need to retest me to check themselves. I could go to the GP and ask for the tests directly which would be free for me but even as someone with a long running history of recurrent low iron and anaemia I find it can be a struggle to get the GP to test my iron levels.
I guess I also just get the vibe that many doctors don't much like patients who read up on things too much or go and get private testing then come to them looking for help.
