Fibromyalgia Diagnostic Criteria

Fibromyalgia is known as an invisible illness because there are no physical indications of the chronic illness. People with fibromyalgia can experience a wide range of symptoms in varying degrees; however, despite the severity of the pain, there is no one test for fibromyalgia. The way to diagnosis the illness is by using the fibromyalgia diagnostic criteria.

The Old Diagnostic Criteria

In 1990, the American College of Rheumatology (ACR) established the diagnostic criteria as having the following points:

  • Widespread body pain in four quadrants of the body for at least three months, and
  • pain in a minimum of 11 out of 18 tender points.

What is the new fibromyalgia diagnostic criteria?

In 2010, the ACR established the new fibromyalgia diagnostic criteria as having the following points:

  • no longer use tender points
  • pain is widespread
  • accompanying symptoms such as fatigue, sleep problems, and not being able to think clearly
  • physical and interview examinations using the widespread pain index (WPI) and severity scale (SS)
  • use of the WPI and SS for cognitive symptoms
  • use of a 42 question survey

The combination of the above fibromyalgia diagnostic criteria is used to determine a fibromyalgia diagnosis. Before making a fibromyalgia diagnosis, your physician should first rule out other possibilities.

      A lot of people do not, and I hope to be one of the people that changes it. Now you are one more person that knows. Thank you!

      Yes, it is. And each time my husband discovers a ‘new’ ailment of fibromyalgia, he is astonished. I am, too, for the most part. Thank you for reading!

    So glad I came across your blog! I didn’t realise there was new diagnostic criteria for fibromyalgia.

    I’ve met criteria for fibromyalgia for years but my rheumatologist hasn’t given me a diagnosis. I asked her about it and essentially the issue is that I have symptoms and signs of a spondyloarthropathy and lupus, but don’t fit into any of the boxes properly. She’s being cautions, but it’s frustrating to be unwell and not have any real explanation to give people!

      I know it’s frustrating, but it’s good that your doctor is taking time with a diagnosis. Many times people are misdiagnosed with fibromyalgia when they are more serious issues. I hope you get a diagnosis soon so that you can be on the road to healing soon. Thank you for stopping by! Please let me know if you have any questions.
