I'm truly amazed at how consistent the readings are with this thing -when compared with my keto strips. Amazing!!
I tried it this morning. Non-keto wife blew 0.00..I blew 0.05. I tested blood ketones at the same time and got 2.4 so..I would say anything over 0.00 would equal some sort of nutritional ketosis.
Fun to use at parties and works great
Works as described thanks.
