Table 3 Precision and accuracy of plasma thymidine assay; acceptance criteria ±15 % for CV and RE (±20 % at LLOQ)

From: The relationship between endogenous thymidine concentrations and [18F]FLT uptake in a range of preclinical tumour models

QC Theoretical thymidine concentration (ng/mL) Calculated thymidine mean concentration (ng/mL, n = 6) CV (%) RE (%)

Medium 40 47 13 −5.4
High 450 462 1.7 2.6
