While there is no degree requirement to become a phlebotomist, associate's and bachelor's degrees are available. Phlebotomists do blood work that is used in laboratory testing, blood transfusions and medical studies. They work at blood banks, hospitals, laboratories and neighborhood health centers. Although no education is mandatory to be employed as a phlebotomist, most hold an associate's degree in the field or have completed phlebotomy training as part of a bachelor's degree program in a health-related field, such as nursing.
