[|Human|] hi,Actually my father is getting recurrent fluid in lungs. X-ray report says its "Plerual effusion" and we have gone thru the test like CT scan, PET/CT scan and Bronoscopy. Everything was normal. But in the beginning ADA cells range was 196. Now it has come down to 55. May i know what can be the reason
[|AI|]  Thanks for your question on Chat Doctor. I can understand your concern. There are two thin pleural layers surrounding lungs. When fluid accumulates between these layers, it is known as pleural effusion. ADA (adenosine Deaminate) is an enzyme found in lymphocytes. So ADA measurement in pleural fluid indirectly suggests lymphocytes activity in fluid. So ADA value of 196 is suggestive of lymphocyte rich pleural effusion. And most common cause for this is tuberculosis. And in TB there is recurrent pleural effusion. So better to consult TB specialist and get done pleural fluid AFB culture and sensitivity report for tuberculosis. Don't worry, he will be alright with anti TB Chat Doctor.  Hope I have solved your query. I will be happy to help you further. Wishing good health to your father. Thanks.
