A test developed by researchers at the University of Washington (UW) uses a single drop of blood and a smartphone vibration motor and camera to determine whether the blood clots too easily, or not at all.
The system features a plastic attachment that holds a small cup beneath the phone's camera. A drop of blood is added to the cup, which contains a small copper particle and a chemical to start the clotting process, after which the phone's vibration motor shakes the cup.
The camera monitors the particle's movement, which stops as a clot forms.
Tests of the system showed that it fell within the accuracy range of commercially available tests.
WU's Shyam Gollakota said, "Almost everyone who has a phone can use this. All you need is a simple plastic attachment; no additional electronics of any kind."
