When are ketones serious?
An hour and a half ago (3 hours after dinner) my sugar was 564. I corrected according to my insulin pump's recommendation. My last check read 495 (30 minutes ago). I just tested for ketones, and the strip came up showing a small amount of keytones.
1) I just noted the bottle of ketone strips expired in December 2008 (6 months ago). Would this lead to an inaccurate result?
2) Is this cause for an emergency? At what point should I go to the ER? I don't want to overlook DKA.
I haven't been throwing up or anything, and I have no signs of illness (besides a headache that just won't go away). I have a slight metallic taste in my mouth (which my boyfriend just said he could smell).
Any advice would be appreciated. I've had diabetes for 5 years and this is the highest my sugar has ever read. Thanks!
