Sedimentation Rate (Sed Rate)

Sedimentation Rate (Sed Rate)

What To Think About

  • Even though some problems, such as giant cell arteritis, almost always cause a high sedimentation rate (sed rate), the test can't be used by itself to identify a specific disease. Results of a sed rate test are considered along with your symptoms, other test results, and medical information.
  • Some diseases that cause inflammation do not increase the sed rate, so a normal sed rate does not always rule out a disease.
  • Some doctors use the C-reactive protein (CRP) blood test instead of the sed rate test to help identify inflammatory conditions. For more information, see the topic C-Reactive Protein (CRP).
