Fig. 4. Device performance comparison with Reference Methods: bias and imprecision.

Fig. 4.

Bland-Altman plot showed that the bias and imprecision of the digital microfluidics (DMF) method to: (A) Reference Method 1, which showed only +0.04 with an imprecision of 2.90 U/g hemoglobin (Hb) of n = 46 subjects; (B). Reference Method 2, which showed that the bias of the DMF method was +0.67 U/g Hb and standard deviation of the difference was 1.55 U/g Hb of n = 40 subjects.
