When you think about it, blood glucose meters need to be shockingly precise. Let's take a real-world example to illustrate this.
This morning, my glucose levels were 6.7mmol/L. What does that mean? Let me dust off my high school chemistry and bust out a calculator.
The internet tells me that glucose has a chemical composition of C6H12O6, which would give 1mmol of glucose a mass of about 180mg (0.18 grams).
A reading of 6.7mmol/L means that in a litre of blood, there would only be about 1.2 grams of glucose.
For perspective, a litre of water is 1000g. I don't off hand know the density of blood, but I imagine it's not too far off.
My meter was able to tell this from a drop of blood.
That's pretty wild. Can someone check my math on this?
