Anti-CCP antibody 와같은새로운진단혈청검사들이개발되었으며이를진단에포함시켜야한다. Early RA 진단이어려워 DMARDs 의조기적용이안된다. DMARDs 보다강력한 TNF-a blocker 등이개발되었으며, 조기사용시관절파괴를막을수있다 ACR/EULAR 진단기준개발의목적 만성또는골미란의 risk 가있는 early inflammatory arthritis 를조기에진단하기위해. Early RA 환자에서 DMARDs 사용의근거를제공하기위해. New serologic test 를진단에적용하기위해. Scoring system 의도입으로진단의객관성을얻기위해. Later course of RA 환자의진단을배제하지않는다.
