My ketones on Thursday was 5.7, I couldn't check my blood glucose as my machine was broken and had to use someone else's for checking ketones. Today my ketones were 3.1, but when I checked my blood glucose levels (as I got a new meter), they were 11.8 (which is where I was told I am suppose to be) I was told that when my ketones were high it means my blood glucose levels are high. So I don't understand why they were high when my blood glucose wasn't??? Can someone explain this? I have been taking my insulin like advised.
