Table 1.

The LFA results were read via a smartphone-based in vitro diagnostics device. The device reads relative intensities of the control line and test line produced on the LFA. (A) Intensity readouts from the device for NTC and cDNA LFA results. The intensity of the test line decreases as the concentration of the sample decreases. The ratio of test line vs control line is a measure for the difference of intensities between the test and control lines for each LFA. (B) Relative intensity measures of control lines and test lines for NTC and RNA LFA results
