Analysis of human trial samples (A) Linear calibration curve for 21 human serum samples with R2 = 0.91. T/C ratio = a[25(OH)D3] + b where a = −0.075 and b = 5.689 (B) ROC curve obtained with Delong method with n = 300000 and auc 0.836 at a cutoff of 50nmol/L (C) ROC curve obtained from Delong method with n = 300000 and auc 1 at a cutoff of 30 nmol/L (D) Calibration curve from 6 human finger stick blood samples with R2 = 0.94. T/C ratio = a[25(OH)D3] + b where a = −0.033 and b = 2.9925.
