Validation of SWEATSENSER with standard reference method for human subject samples. (A) PharmChek sweat patch worn by subject on arm. (b) Schematic of sweat sample collection using patch for correlation of SWEATSENSER with ELISA. (c–f) Pearson's correlation between SWEATSENSER and reference ELISA method with Pearson's correlation coefficient r = 0.99 for all biomarkers from n = 26 healthy human subject measures. (g–j) Bland–Altman analysis between SWEATSENSER and ELISA from n = 26 healthy human subject measures with a mean bias −1.99 pg mL⁻¹ IL‐6 (g), −9.43 pg mL⁻¹ IL‐8 (h), −0.5 pg mL⁻¹ IL‐10 (i), and 0.55 pg mL⁻¹ TNF‐α (j)
