There is no single test for psoriatic arthritis (PsA). Your doctor will ask you about your symptoms and do a physical exam. The doctor may also order tests, such as:

  • blood tests
  • radiographic tests: X-rays (see Figure 1) or magnetic resonance imaging (MRI; the use of a magnetic field and radio frequency pulses to view tissues and organs inside the body - see Figure 2)

Radiographic tests give your doctor a picture of how PsA is affecting your joints, bones, and nearby tissues over time (also called radiographic progression). They can also help your doctor see how your treatment is working. Ask your doctor about your radiographic progression.
