." >> o'brien: at the university of washington i met virologist alex greninger, who'd been trying tojust that. >> you got to have the supply of testing, absolutely do. we need to bable to detect where the virus is and then try and snuff it out, i mean, right? prevent its transmission, that's the name of the game in the coming months. >> o'brien: but hean into a bureaucratic brick wall: the food and drug administration had instituted emergency procedures to make sure any new tests were accurate. >> you can make your own tests, but you have to send it to the fda and get it reviewed and then authorized. and i'll admit, i'm in my first couple of years here in this particular job, i had not beenth rough this process before. >> o'brien: e fda application was 28 pages long, and required ulhim to run tests that wotake at least two weeks. and that wasn't all. >> one of the thin is they needed a document fedex-ed across the country before they could look at the docunt. >> o'brien: you couldn't electronically transmit it? >> i could electronically transmit it, but they couldn't look at it until

greninger, to that point, a lot of people saying these tests will be a key part to us getting back toome sort of normal, allowing people to go back to work and school and all of those things. what are your thoughts on the antibody test and any caution you may feel? >> if you like the antibody tests are very important. we're definitely working on it right now, trying to get different tests, test manufacturer kits and to evaluate them. antibody testing takes a little bit more interpretation. you have to figure out where to make your cut off. you have to figure out if it's specific, there are other coronavirus is that it can cross-react with. there's more interpretation to it. you have to know that people are actually protected and that takes following people, it's not just a simple text. we have to slow a little bit on the serology so we can understand before we scale something was not good. and then we have to worry about how we can scale it so everyone can get tested. it really serology right now is in the same place that btr was about five weeks ago. >> shannon: so we need some time.
