Figure 2From: "Random" gentamicin concentrations do not predict trough levels in neonates receiving once daily fixed dose regimens Validation Cohort: "Random" Gentamicin Concentration v Time. "Random" gentamicin concentrations from 39 validation babies plotted against the cut off line derived from Figure 1 (see Text). Safe 24 hr concentration = ≤ 1 mg/l. High 24 hr concentration = >1 mg/l.Back to article page
