A smartphone algorithm with inter-phone repeatability for the analysis of colorimetric tests

A smartphone application algorithm with inter-phone repeatability was developed for both Android and iOS operating systems. The app transformed the smartphone into a reader to quantify commercial colorimetric urine tests with high accuracy and reproducibility in measuring pH, protein, and glucose. T...

More Information
Summary:A smartphone application algorithm with inter-phone repeatability was developed for both Android and iOS operating systems. The app transformed the smartphone into a reader to quantify commercial colorimetric urine tests with high accuracy and reproducibility in measuring pH, protein, and glucose. The results showed linear responses in the ranges of 5.0–9.0, 0–100mg/dL and 0–300mg/dL, respectively.
