Cue, a San Diego-based startup, unveiled its product of the same name this past May. The 3-inch tall device takes a drop of saliva and analyzes it for five molecules: C-reactive protein (CRP) a marker for inflammation in response to stimulus like injury or chronic illness; vitamin D; luteinizing hormone (LH), a marker for fertility; influenza; and testosterone. The tests take a few minutes, with results sent to the user’s smartphone.
