The latest marker introduced for detection of RA is anticyclic citrullinated peptide (anti-CCP), which can help in early diagnosis and check the progression of severity of RA.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Aim:<\/jats:title>\n                    <jats:p>The present study was designed to evaluate the role of anti-CCP antibody in the diagnosis of RA in early stage of disease as compared to ESR and CRP.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Materials and Methods:<\/jats:title>\n                    <jats:p>The study population consisted of 325 participants presenting to the orthopedic department, AIMSR, with suspected clinical features of arthritis.
