"make blood tests simple, timely, unalarming and cheap" sounds pretty valuable to me. I suspect there are billions of people who rarely, if ever, have blood tests (impoverished areas, children). And then in developed areas, I could easily see blood tests becoming a daily thing (or multiples daily). Athletes might do them every few minutes. Etc.
