Labwork while sick?

I'm coming down with something...sneezing, coughing, runny nose, plugged up ears, headache. 

Was planning on getting my first round of labwork done tomorrow morning, but now I'm wondering....should I wait to see if this turns into something or do it now before it does?

I couldn't see why  ....

If you have an infection, it can mess with certain levels.  Makes some of them seem lower than they are and some higher than they really are.  Makes labs really difficult to interpret.  If you're really, truly sick with a cold...I'd wait.  If it's just allergies or something though, it should be fine.
