[|Human|] I have a lung problem.  My Rheumatologist thinks rheumatoid has settled in my lungs.  Had rheumatiod for 16 years, but blood test are all negative.  Dr. cant tell what it is by X ray.  I will see a thorasic surgeon to tlak about a biospy.  Could I have rheumatoid in my lungs and it not show up on blood work?
[|AI|]  Thanks for your question on Chat Doctor. I can understand your concern. Yes, it is very common to have Pulmonary manifestations of rheumatoid arthritis (RA) without abnormal blood reports. And to confirm this you need to consult pulmonologist and get done 1. Clinical examination of respiratory system 2. PUT (Pulmonary Function Test). 3. HRC (high resolution CT) thorax. RA can cause bronchitis, fibrosis, bronchiectasis etc. So PFT is needed for the diagnosis of bronchitis. HRCT thorax is needed to rule out fibrosis and bronchiectasis. So consult pulmonologist and discuss all these. Hope I have solved your query. I will be happy to help you further. Wish you good health. Thanks.
