Pre-transfusion hemoglobin level on day 1 (d1) was 8.9 g/dl (Figure 1) and the reticulocyte count was 5.67% (corrected count 1.75%), while LDH was 212 IU/L (normal range<246 IU/L). On d32, the hemoglobin continued to drop to 4.6 g/dl, while the reticulocyte count was 4.71% (corrected count 0.8%) (Figure 1).
