2. Figure 1
Correlation between the DBS method and conventional method for busulfan (A) concentration and (B) AUC0–∞. Blood samples for analysis were collected at 2, 4, and 6 hours after the start of infusion. Correlation coefficients for A and B were R2 = .9837 (y = .9903x, P < .01) and R2 = .8725 (y = 0.9986x, P < .01), respectively. Sampling was from 10 patients.

3. Figure 2
Effects of hematocrit value on the divergence between blood busulfan concentrations obtained with the DBS method and conventional method (y = .2847x − , R2 = .0539, P = .52). The hematocrit range was 18.2% to 34.1%.
