Fibromyalgia: Understand how it's diagnosed

Tests that may be needed

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
  • Anti-nuclear antibody
  • Celiac serology
  • Vitamin D

Your doctor may also perform a careful physical exam of your muscles and joints, as well as a neurological exam to look for other causes of your symptoms. If there's a chance that you may be suffering from sleep apnea, your doctor may recommend a sleep study.
