Correlations between blood volume and lean body mass and body surface area. A, blood volume (ml) plotted against lean body mass (kg) in girls (●) and boys (○). B, blood volume (ml) plotted against BSA (m2) in girls (●) and boys (○). The normal range is defined as twice the standard deviation and is identified by the dashed lines.
