The challenge for the homebrewer is to build something traceable. When you measure blood sugar today the same sample should yield the same number - not only today but also ten years from now. Yes, Theranos is fighting with traceability, too.
- danielschonfeld 11y agoPerhaps i phrased my question wrong. Are those test strips connectable in any way to a home-brew device?
- HarryHirsch 11y agoCan't see why not. Buy a pack, start experimenting. You need to sense current, not voltage, so it will be a resistor and scope, not just a scope. Good luck! The chemistry is established; the amount of glucose is proportional to the charge that will flow through the thing.
- danielschonfeld 11y agoI didn't realize thats how it works... I guess i was hoping for something more like what the CGMs offer thats continuous and forever. I'm just so annoyed with the prices of these CGM devices and their sensor replacement costs.
