Hi Wendy,

Yes, any colour change means you are in ketosis. And you can even be in ketosis and not change colour on the strips at all.

If you go to "Low Carb Tips" on the orange bar at the top of the screen, you'll see (along with lots of other great info) an article by our Doreen T called Ketosis and Ketone Test Strips which will explain more to you.

Cheers.

Rosebud
