I (and others here) were diagnosed back in the pre-home-bg-test days where peeing on strips (or in test tubes… what were the little tablets called? I remember Testape strips but can’t remember the name of the little fizzy tablet that got hot) multiple times a day was the only way to get even a vague guess at what our control was.
I don’t carry Ketostix around with me (I do have some at home) or use them very often. I have some but I might go years between actually bothering to use them. bg testing is so way better at figuring things out 99.999% of the time. I’m not saying there’s no circumstances where a Ketostix reading might be useful but in my head they are mostly in the “stone knives and bearskins” days back when I had to pee into a test tube and they taught me how to boil glass syringes and sharpen needles.
