Abstract
Monitoring serum phosphate level is critical for patients with kidney disease and those undergoing dialysis. We report a POC serum phosphate measurement device, by integrating a disposable paper-based microfluidic chip with a smartphone-based measurement system. The inexpensive microfluidic chip collects a droplet of blood from the patient and isolates the serum, which then reacts with a malachite green reagent, resulting in a colorimetric change, measured using a smartphone-based device. This POC instrument was tested on clinical samples obtained from patients undergoing dialysis, and we observed a strong statistical correlation between our results and the tests performed in a clinical laboratory.
