While AS can be diagnosed through the description of radiological changes in the sacroiliac joints and spine, there are currently no direct tests (blood or imaging) to unambiguously diagnose early forms of ankylosing spondylitis (non-radiographic axial spondyloarthritis). Diagnosis of non-radiologic axial spondyloarthritis is therefore more ...
The BASDAI or Bath Ankylosing Spondylitis Disease Activity Index is a validated diagnostic test which allows a physician, usually a rheumatologist, to determine the effectiveness of a current drug therapy, or the need to institute a new drug therapy for the treatment of Ankylosing spondylitis (AS). The BASDAI is one of a group of classification ...

Axial spondyloarthritis can be divided into two classes: Non-radiographic axial spondyloarthritis (nr-axSpA): This term encompasses both the early disease stage of ankylosing spondylitis, in which no radiographic changes are visible yet, as well as less severe forms of ankylosing spondylitis. Radiographic axial spondyloarthritis:
Age is one of the main risk factors for arthritis. As the U.S. population continues to age, the prevalence of arthritis is expected to increase as well. ... Ankylosing spondylitis. Lupus arthritis ...
Among the genetic factors that may influence ankylosing spondylitis, the HLA-B27 gene accounts for about thirty percent of the overall genetic risk, per the National Library of Medicine. The ...
X-rays, MRIs and other medical imaging tests can be used to show signs of inflammation and damage within the SI joints. Typically, a spine specialist will order a medical imaging test if they suspect ankylosing spondylitis or another form of arthritis to be the primary cause of inflammation and pain. [citation needed]
Patrick's test or FABER test is performed to evaluate pathology of the hip joint or the sacroiliac joint. [1] The test is performed by having the tested leg flexed and the thigh abducted and externally rotated. If pain is elicited on the ipsilateral side anteriorly, it is suggestive of a hip joint disorder on the same side.
