Hi guys, I'm going to start Drexel's accelerated nursing program in April 2019, and clinicals are supposed to start early April. I already got the Hep B series in 1999-2000, which means I was about 3 or 4 years old at the time. I have not gotten the titer done yet, but the program says I am supposed to provide proof of a positive titer. Now I'm getting worried because it's about 4 months away from the program and I just realized I have to get this titer done. Is it likely that this could come back negative? Would that mean I need to complete the series all over again?
