Testing

Instruments for measuring ketosis rather than guessing at it.

Urine reagent strips are the cheapest entry point and they are useful early, when the body is spilling ketones it cannot yet use. They become unreliable once you are fat adapted, and they lose accuracy within days of opening the tube.

For a real Glucose Ketone Index you need blood glucose and blood ketones, not a strip. The KetoNoir app calculates GKI automatically once both readings are logged.
