In theory lab on chip testing may reduce costs greatly, yes.<p>The harder(or maybe impossible) part is collecting clean samples from the fingertip. But maybe theranos will pivot to collect blood via veins, at least for now ?<p>That of course will reduce their valuation greatly(because people hate vein-puncture, so no frequent blood testing scenarios), but the cheap price could be very valuable to third world countries.<p>But again, that&#x27;s just theory.
