Rheumatoid arthritis (RA) diseases generally diagnosis referred from patient symptoms, Physical examination, x-rays, Scans, Biopsy test and blood test. In this paper comparative analysis of two different methods for diagnosis of RA has been done. First method deals with diagnosis of RA using image processing and another method was using non invasive bio impedance technique. During both methods synovial fluid level was considered as common based. Study has been done on impact of synovial fluid on diagnosis of arthritis using image processing and non invasive bio impedance method. https://biomedpharmajournal.org/vol7no1/comparative-study-of-rheumatoid-arthritis-diagnosis-using-two-method/ Rheumatoid Arthritis Synovial Fluid Image processing Bio impedance
