The ESR is elevated in patients with rheumatoid arthritis.It decreases when the disease is in remission and increases when it exacerbates;therefore,it is useful for monitoring this disease.It is normal in the first 24 hours of acute appendicitis,so is not useful in diagnosis.It is elevated in multiple myeloma,but also in many other clinical conditions,so it is not diagnostic for it.It is normal in osteoarthritis and thus of no value for monitoring those patients.
