The TG-ROC for DSe and DSp for each dilution are shown in Figure 1. The value of the DSe and
DSp at the intercept increased with the dilution of the sample, reaching 100% at a colostrum dilution
of 1:500. The DSe, DSp, and S/P threshold at the intercept for each dilution were: 33% at an S/P ratio
threshold of 2.10 for undiluted colostrum (Figure 1a), 56% at a 1:5 dilution colostrum at an S/P ratio
threshold of 2.60 (Figure 1b), 93.9% at a 1:100 dilution colostrum at an S/P ratio threshold of 2.20
(Figure 1c), 93.9% at a 1:200 dilution colostrum at an S/P ratio threshold of 1.90 (Figure 1d), and
100% at a 1:500 dilution colostrum at an S/P ratio threshold of 1.65 (Figure 1e).
