Diagnosis of Enteropathic Arthritis

A diagnosis of enteropathic arthritis is made through a complete medical examination including a history of symptoms and taking into account family history. Various tests may also be done to determine the presence of an inflammatory bowel disease and inflammatory arthritis.

Medical Exam

Besides examining a full medical history of symptoms and taking a thorough family history, various tests may be performed:

  • A stool culture may be taken if a diagnosis of an inflammatory bowel disease (IBD) such as ulcerative colitis and Crohn's disease has not yet been established.
  • A colonoscopy with or without bowel biopsies may also be done.
  • Blood tests may be done including an erythrocyte sedimentation rate (ESR or SED Rate), which may help in detecting inflammation, a test to determine the presence of the HLA-B27 genetic marker, and/or a C-reactive protein, which is another test that may help detect the presence of inflammation in the body.
  • Synovial fluid (fluid that lubricates the joints) may be taken from affected joints for study.
  • X-rays of affected joints may be taken.
