Has anyone had to have a blood test as part of getting their marriage license? If so, what was the process of it? Was there a specific place you had to go to as part of the application process with a nurse or something, or could you just get a doctor or someone to sign off on it?

Basically, I'm wondering how a couple with a certain secret could deal with this particular road block on their way to wedded bliss.

Any information would be helpful.
