Tests and Procedures
Sed rate (erythrocyte sedimentation rate)
What you can expect
The sed rate is a simple blood test. You don't need to fast before the test.
A phlebotomist, nurse or medical assistant will use a needle to draw blood from a vein, most likely a vein in your arm. After the test, the site on your arm might be tender for a few hours, but you'll be able to resume most normal activities.
