The author didn't ask for ones proven to work; everything's specious until a successful startup makes it obvious. And I would definitely pay for on-demand on-site phlebotomy for a number of reasons, if I was to need one, and I bet you would too. People get blood drawn when their body isn't working right and nobody's sure why. Whether you're coughing up blood, can't see straight, or can't walk, getting your butt into that clinic is a major pain point. Maybe you have a high-stress low-skill job like at a package sorting facility, where you come in late, you get canned. Doesn't matter that you'd have to blow a day's wages to save two hours' working time- that's just how the economics work for some people (talk to cabbies and you'll find many of their clients are very poor, even though cabs are ridiculously expensive). And as far as the time premium, it's downright scary when your health takes a sudden turn. Hours count when you have what could be fast-advancing cancer, or an aggressive bacterial infection. An extra $30 to shave a day off the time until I get results? Easily justified.
