I understand your desire to raise awareness of this condition. It is my understanding that, in 2016, the UK's independent expert screening committee recommended against screening for Haemochromatosis in adults. 
While this is clearly a serious condition, the genetic fault that causes Haemochromatosis does not cause ill health for everyone, and I agree that in such cases screening could cause unnecessary worry and anxiety. That said, I understand that Public Health England and the UK National Screening Committee are due to review these recommendations again in 2019.
