Hi Jay, it's a good question. Not the author but a (former) biologist so I'll take a stab. Once the RNA is in your blood it diffuses around your system pretty quickly and begins stimulating an immune response - there is no way to just isolate and extract the RNA at this point, the cat is out of the bag so to speak. Additionally, RNA has very short half-life, much shorter than an exosome or cell. So even if you could isolate/extract the RNA it would be all degraded after a day or two (the internet says the half-life is 10 hours).

If I'm off base, can a real biologist correct me?
