When applying for a position that holds the title of a phlebotomist, a phlebotomy certification is not only required but will help you get the upper hand. The certification shows the employer that you are totally qualified for the job. It shows that you have reached the standards set by the certifying bodies in the medical field for the education and experience needed in order to perform the job properly. The three certifying bodies include the American Society For Clinical Pathology, Association of Phlebotomy Technicians, and the National Phlebotomy Association. Each of these bodies hold acceptable and widely recognized certifications.
