Dang...yes, I hadn’t thought of that..I am still having to get used to thinking about things like that.
My granddaughter’s bs goes high so often that I am always having to test her ketones...I think she hates that more than testing her blood.
My youngest son had childhood lipoid nephrosis when he was little, and I had to test every urination for blood, but the stick also contained reagents for sugars, ketones, and other tests. The sticks are expensive, but they are a good investment.
