Hello. I had a sickness bug 2 days ago and mu sugar waa ranging between 17 and 23. I counter acted it with insulin. Ive bren type 1 for 36 years. I am 48. My cassette on my blood machine expired today my fault as i should of re ordered but being ill i didnt. So i had some ketone tests and ive just done it and it was 2.6 ive took extra humilog but i have no way of measuring my bloods. Do i go to A & e or am i a time waster. Really unsure what to do.
