Figure 1 Accuracy of blood spot GFR relative to serum GFR. (a) Correlation between iohexol serum GFR and blood spots GFR (ml/min/1.73 m2) calculated according to single-compartment analyses and corrected by the Brochner-Mortensen equation. (b) Analysis by Bland–Altman plot demonstrates that the difference between the two measurements (y axis), finger prick and serum showed a bias of -1.17, which did not significantly change with changes in the degree of GFR (x axis).
