A new health-tracking device may cut down on your doctor visits, said Ainsley O'Connell at Fast Company. The gadget, called Cue, "puts lab-quality medical testing in the hands of consumers." Using the swab-like wand, Cue users can take biofluid samples from their nose and "load the wand into a pale green cartridge roughly the size of a thumb drive." The sample is then analyzed, and test results are delivered to a Bluetooth-paired smartphone app within minutes. The system "will be able to test for fertility, influenza, inflammation, testosterone, and vitamin D."
