A full third of patients never follow through with their doctors’ requests to get blood drawn for important tests. What if, instead of schlepping to the lab, the lab came to you? That’s the idea behind Richmond, Virginia-based Iggbo, a startup that aims to make drawing blood for medical tests as easy as ordering car service. Like an “Uber for blood,” Iggbo lets doctors order blood draws at the touch of a smartphone app. A patient then schedules a convenient at-home appointment online, and a phlebotomist gets dispatched.
