Usefulness of the ESR
The Erythrocyte Sedimentation Rate (ESR or Sed Rate) is one of the most widely used laboratory tests throughout the world, the usefulness of which has been reported by many workers as a screening test for general illness, (1-4) or as a marker that can reflect the severity of acute inflammatory disease. (5)
Monitoring disease and diagnosis
For many years the ESR has been used as part of the monitoring process for patients with temporal arteritis and it is accepted to be of some diagnostic value when taken into consideration with other factors in both this condition and rheumatoid disease. (6-7) The test may also be used as an aid to monitor therapy in these conditions. In chronic renal disease, changes in the ESR appear to be due to alterations in fibrinogen concentrations and the constituents of uremic plasma, independent of the degree of anaemia. (8)
The ESR can also be used as a prognosis marker, as shown by a study of ischemic stroke, which indicated that a high ESR on admission was associated with clinical deterioration during the first 24 hours of stroke onset. (9) Conversely patients with congestive heart failure who had higher ESR values, had better haemodynamic and clinical benefits. They also had better one and two year survival rates. (10) A high ESR in patients with non-metastasising renal cell carcinoma has been shown to indicate a poor prognosis. (11) Another study monitoring early stage Hodgkin's disease has shown that the ESR could identify a group of patients at high risk for relapse and subsequent death. (12)
