ELISA tests don’t need to be done at central lab facilities; there are plenty of machines on the market with varying levels of automation (and many already in hospitals, even in ones that aren’t particularly outstanding). I’m curious what barrier to scaling those with COVID (either by making more of these machines, or repurposing other test capacity) you’ve identified that makes bringing a totally new machine to market more attractive, from a scaling perspective.
