Wonder where test blood comes from? For the past year or so, whenever I've donated blood, there's an extra page in the donor materials that explains how a sample of each unit goes to research for developing new tests for Zika. (It's a different Zika research project, I'm sure.) If you want to help researchers developing new blood tests for emergent diseases (or need another reason to donate blood), it's here and it's easy and free. I think that's cooler than anything I'll ever do with technology.
