Iirc the problem with Theranos' strategy was that the fingertip blood has highly variable composition compared to mainline blood. For example, getting lipid counts would be off. I would believe you can accurately count the blood cells in your fingertip, but I (a layman) would need a bit more to believe that this is necessarily representative of mainline. It might still be diagnostically useful.

> I would believe you can accurately count the blood cells in your fingertip, but I (a layman) would need a bit more to believe that this is necessarily representative of mainline. It might still be diagnostically useful. I'm skeptical of that, since my impression is that the many of the capillaries in one's finger are so tiny that only one blood cell can fit through at a time. That seems like something that could fuck up the results, but I'm no doctor or biologist and it sounds like regulators might actually be paying attention this time around.
