Could I have rheumatoid in my lungs which does not show up on blood work?
Patient: 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. can't 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? Doctor: Thanks for your question on Health Care Magic. 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. PFT (Pulmonary Function Test). 3. HRCT (high resolution CT) thorax. RA can cause bronchitis, fibrosis, bronchiectesis etc. So PFT is needed for the diagnosis of bronchitis. HRCT thorax is needed to rule out fibrosis and bronchiectesis. 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.
