Researchers develop an STD-detecting accessory for your smartphone

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.

During that pilot study, healthcare workers successfully tested 96 patients after only 30 minutes of training. The researchers estimate the dongle could cost as little as $34 to manufacture, making it exponentially more affordable than traditional testing equipment.
