high blood sugar?

Ja
I have been having a lot of tests done on my heart. Those came back great but I also did blood work and it came back great except for I ate 2 hours before. They didn't tell me I was supposed to fast. I ate McDonald's and had a sweet tea and my blood sugar was 114. They said it was high? I am only 23 and not over weight at all. Just a little worried I guess
