How is ankylosing spondylitis diagnosed?
In addition to reviewing medical history and carrying out a physical examination, a diagnosis of ankylosing spondylitis can made by: • An X-ray to identify any changes in bones and joints; • A computerized tomography (CT) scan to assist with early diagnosis; • A magnetic resonance imaging (MRI) scan to enable visualization of the inflammatory changes in the sacroiliac joint and the spine; • Blood tests to check for an increase in inflammation, and; • Genetic testing to check for the presence of the HLA-B27 gene.
