Performed
Sunday – Saturday, 24 hours a day.
Results available within 2 hours.
Reference Range
0-18 mm/hour for women.
0-15 mm/hour for men.
Test Methodology
Dearborn, Farmington Hills, Grosse Pointe, Royal Oak & Troy:
iSed Photometric Rheoscope.
Trenton, Taylor, Wayne:
Fisherfinest Sediplast (Westergren method)
Interpretation
- Samples containing sickle cells, spherocytes, lipemia, or cold agglutinins may give false results.
- Anemia may cause a falsely elevated value in some patients (for the methodology other than iSed Photometric Rheoscope). There is no effective method for correcting anemia in the Westergren method.
Clinical Utility
The erythrocyte sedimentation rate reflects changes in plasma proteins which accompanies acute and chronic infections, inflammation, malignancy, multiple myeloma, macroglobulinemia and hyperfibrinoginemia. The erythrocyte sedimentation rate is used primarily to follow the progress of inflammatory diseases such as rheumatoid arthritis during treatment.
