I am a patient of rheumatoid arthritis. I consult doctor and start some of medicine 6 month. But my esr (36 to 27) and some other level are still up and down. So doctor tell me if your tb report is normal than we started biological medicine. But my tb gold lithium heparin report come 1.41 and doctor says before we started biological medicine for arthritis first we solve latent tb. But my lungs are completely normal and the physician says I don't need any kind of tb therapy. I also do mantoux test result is 2 and normal. My question is can I start therapy of biological medicine in arthritis or constant other tb specialist?
