Should I become a phlebotomist prior to nursing school? I'm currently working on my pre-requisites for an ABSN program. I'm considering going to phlebotomy school (12 weeks, $1800) before I attend nursing school. Becoming a phlebotomist will grant be the experience I need, while earning enough living income. I'm not sure if the investment to become a phlebotomist would be worthwhile. I intend on beginning nursing school during the summer of 2017.
