Hepatitis B virus core antibody (HBcAb) and anti-hepatitis C virus (anti-HCV) calibration curves and sensitivity ratios for Whatman903 and HemaSpot samples relative to serum samples. The graphs depict the calibration curves and sensitivity ratios for (A) HBcAb and (B) Anti-HCV and plot the dilution ratio (x-axis) versus the COI (y-axis) for different dilutions (undiluted, 2-fold, 8-fold) and different types of DBS (Whatman903 at one drop/circle and two drops/circle and HemaSpot).
