And, for bonus points, how are they made?
These seem like an awfully important test piece. I’m pretty sure they’re just checking for glucose with some enzyme or something. But who knows, maybe its something simple or everyday? Are all brands using the same materials?
I don’t think the strips themselves do anything but hold your blood for the actual tester you put them in.
I’m pretty sure the test strips strips probably do most of the testing, and the meter just reads the result.
