Thanks to engineers at Columbia University, you might soon be able to test yourself for HIV and syphilis using only your smartphone. Scientists there have developed a dongle that can produce results via an on-screen app in just 15 minutes, using only blood from a finger-prick.
The device, which simultaneously tests for the HIV antibody and two markers for syphilis, can replace traditional in-lab tests by drawing power from the smartphone. Its ability to function independent of grounded electricity means it may be incredibly beneficial to areas with scarce access — including Rwanda, where it was initially tested.
