Fig. 3. Device performance comparison with Reference Methods: linear correlation.

(A) When measurements using the digital microfluidics (DMF) method were compared to those of Reference Method 1, a correlation (r) of 0.95, with a slope of 0.95 and y-intercept of 0.34 was found. The majority of glucose-6-phosphate dehydrogenase (G6PD)-deficient samples (88.2%) were from males (15/17). (B) When measurements using the DMF were compared to those of Reference Method 2, a correlation (r) of 0.95, with a slope of 1.08 and y-intercept of −0.32 was found. The majority of samples had normal G6PD enzyme activity.
