Abstract
The development of medical smartphone applications (apps) can allow quantification of rapid diagnostics at point-of-care and enable clinical data collection in real time. Mobile medical apps can reduce the erroneous subjective readouts, and create a standard readout platform with connectivity options at low cost. This chapter demonstrates the development of an app algorithm that utilises the camera of the Android and iPhone smartphones to read colorimetric tests. This smartphone app can be used with dipsticks, lateral-flow and flow-through assays as well as aqueous colorimetric tests that are typically read by spectrophotometers or microplate readers. The mobile app was designed to provide on-site quantitative screening when rapid diagnosis is needed. The utility of the smartphone app was demonstrated through quantifying pH, the concentrations of protein and glucose in commercial urine test strips, which had linear responses in the ranges of 5.0–9.0, 15–100 and 50–300 mg/dL, respectively. The app can be adapted for semi-quantitative analysis of commercial colorimetric tests, rendering it an inexpensive and accessible alternative to more costly commercial readers.
