Triplicate mean IFN-γ responses to limiting dilutions of CEF (10−7 to 2 μg/mL) for six healthy controls measured by manual (◇) and automated (●) ELISpot assays. Assay results were comparable (p>0.05 for all dilutions, Wilcoxon signed-rank test of paired differences in triplicate means), with greater variation at weaker dilutions for both processes (Spearman’s correlation between replicate CV and concentration: r=−0.77 manual; r=−0.64 automated; p < 0.0001).
