There's no way Apple would design any device which would, I quote, "insert a thin, sterile filament into the skin" to draw interstitial fluid. The Abbott sensor is designed to be worn for weeks on end.

How else are they going to monitor blood glucose? Finger prick tests?

  They could miniaturize a specialized spectrometer of some sort I suppose. I don't know. If I knew, I'd be doing it now - that's quite literally tens of billions of dollars that people would throw at you faster than you'd be able to catch it. E.g. https://iopscience.iop.org/article/10.1088/1757-899X/104/1/012036 https://iopscience.iop.org/article/10.1088/1757-899X/104/1/0...

    Yeah, that’d be a very rewarding problem to solve.

  The rumor (based on acquisitions Apple has made) is that it will be based on sweat, using sensors built into new watch bands.

      Looking at Rockley stuff in particular makes me hopeful this could be solved, if it's solvable with spectrophotometry at all. I'd even be OK with something larger, perhaps ankle-worn, as long as I don't have to puncture my skin at all.
