Noise (standard deviation of the baseline, δ) over the cTnI concentration range of 1 to 1000 ng/mL for the direct and sandwich assays, computed using Equations (12S) and (19S) (Supplementary Materials). The worst cases are bolded.

Concentration of cTnI, ng/mL	δ (Direct Assay, g/g × 100)	δ (Sandwich Assay, g/g × 100)
1	0.043	0.315
10	0.055	0.337
100	0.030	0.297
1000	0.061	0.404
