If you don't sleep well would it affect your blood tests?

Bárbara • I`m 29, and I have a beautiful baby girl born on May 30th, 2017 ^^ I also have a dog named Oliver and I love him lots!
I have to do some blood tests on monday and I'm so nervous that when I go to sleep I start thinking a lot about it and it takes me a while to fall sleep, can this change some of the results or sleeping well doesn't have anything to do with that? Thanks! ^^
