Erythrocyte sedimentation rate measurements by TEST 1 better reflect inflammation than do those by the Westergren method in patients with malignancy, autoimmune disease, or infection.
We compared the TEST 1 (Alifax, Padova, Italy) and Westergren methods of measuring the erythrocyte sedimentation rate (ESR) to assess inflammation. The ESR was measured by both methods in 154 blood samples from patients with malignancy (n = 69), autoimmune disease (n = 44), or infection (n = 41). Total protein, albumin, and C-reactive protein (CRP) levels were measured in each plasma sample, and albumin and alpha(1)-, alpha(2)-, beta(1)-, beta(2)-, and gamma-globulin fractions were measured by capillary electrophoresis. TEST 1 ESR values were significantly lower than the Westergren values, by 10.9 mm/h. We found that the correlations of TEST 1 ESR values with inflammatory protein levels (total protein, globulin, CRP, and alpha(1)-, alpha(2)-, beta(2)-, and gamma-globulin) were better than those obtained using the Westergren method. These findings indicate that ESR measurements by TEST 1 reflect inflammation better than do those by the Westergren method in patients with malignancy, autoimmune disease, or infection.
