Invert tube 8-10 times to mix blood with anticoagulant. Please send samples refrigerated. Room temperature samples must be tested within 24 hours of collection.
The Sed Rate (sedimentation rate), also known as the ESR (erythrocyte sedimentation rate) or the Westergren ESR test, measures the distance that erythrocytes, when placed in a standard tube, sediment toward the bottom of the tube during a standard timeinterval. The erythrocyte sedimentation rate is a nonspecific marker of inflammation and may be ordered when the physician suspects the patient's symptoms may be due to an inflammatory process. Additional testing is needed to identify the location andcause of the inflammation.
