Diagnosis

In the past, doctors would check 18 specific points on a person's body to see how many of them were painful when pressed firmly. Newer guidelines don't require a tender point exam. Instead, a fibromyalgia diagnosis can be made if a person has had widespread pain for more than three months — with no underlying medical condition that could cause the pain.

Blood tests

While there is no lab test to confirm a diagnosis of fibromyalgia, your doctor may want to rule out other conditions that may have similar symptoms. Blood tests may include:

  • Complete blood count
  • Erythrocyte sedimentation rate
  • Cyclic citrullinated peptide test
  • Rheumatoid factor
  • Thyroid function tests
