Having been diagnosed with IPF in December a second Consultant and a professor have looked at all of my results including CT scan, X Rays and lung biopsy and have decided I do not have IPF but have actually got ''chronic hypersensitivity pneumonitis''. I'm seeing the Professor on Friday to discuss diagnosis and treatment. I thought a lung biopsy was conclusive but apparently not. How can ''experts'' disagree so widely. (I was also wrongly diagnosed and commenced treatment for TB before the above diagnosis's were made)!
