Maybe this is something everyone knows but new to me. DH started new job this hear and now has private healthcare. I’ve used it on a couple of occasions for me and the children, when we haven’t wanted to wait for a Gp app (2 weeks++ here) or we’re anxious to get something seen to. Every time I’ve ended up being recommended a barrage of tests, from ones that make sense to the severely clutching at straws ones.
Eg 1yo DS was seen for an odd-looking mole on his calf and, while that was given the all clear, we were offered blood tests and a brain scan as his head was at the top end of the centile charts ?!?! (As are his older brothers’!). We refused both. We are a family of big heads (sadly doesn’t translate to big brains!)
DH needed antibiotics to get rid of a chest infections and was sent for lung scan, about 10 lots of blood taken and an asthma test that took about 3 hours in another private hospital. He was told it was strongly recommended. But then the antibiotics did the job and he was fine within just over a week, AFTER all the testing 
These are just the ones that stand out.
Are doctors just being thorough or could they really be so unethical as to recommend unnecessary tests and treatment for £££s?
Again, probably being massively naive but was interested to hear others’ thoughts
