@AceFace why do you think you need to test for ketones?
There seem to be a couple of reasons I have come across:
- those following a very low carb diet look to have ketones to show their body os in ketosis - burning fat instead of carbs
- for people with Type 1 diabetes, we are at risk of DKA (diabetic ketoacidosis) - high blood sugars with ketones is a strong indication of this very dangerous condition. Whilst I have read of people with type 2 experiencing this, my understanding is that it is rare (and potentially a misdiagnosis of type 2).
I have strips to test for ketones but use them very rarely - only when my levels are stubbornly high for a long time.
