Clinical Usefulness of Haptoglobin Levels to Evaluate Hemolysis in Recently Transfused Patients

Table 2

Mean, standard deviation (SD) and mean differences in haptoglobin levels at each time interval. The differences were examined using univariate paired 𝑡-test with only a significant difference found from pre haptoglobin levels and the haptoglobin levels immediately after transfusion significant at 𝑃=.041 (two sided).
