Ok, I feel the need to give more information after reading some of the responses. I have not had my blood drawn yet as my job is contingent on getting through all the red tape that is necessary to work for the federal gov't, so no consents signed yet. I also keep copies of everything, so I have very updated results of titers so they said they wouldn't need to have them done again. HR still said there would be a blood draw, EKG, and physical. I just haven't had such an in depth physical to work in the hospital so I was just curious. I did think that they might draw blood for drug testing but that doesn't make much sense since everything else they are doing is so thorough. Drugs (both illicit and prescription) stay in the blood for very short periods of time but in the urine for a very long time, either way it doesn't matter, I'm not concerned about it, like I said just curious. I was so excited about hearing that I had the job if all went well with the federal background check that when they asked if I had any questions, my mind went blank. Thanks for all the responses.
