Phlebotomists draw blood from patients to be used in tests, blood donations, or research. They follow sanitary procedures to keep patients, and themselves, clean and safe from blood-borne pathogens. Phlebotomists can work in a variety of environments, including hospitals, doctors’ offices, laboratories, and blood donation centers. A postsecondary nondegree award from a phlebotomy program is typically required to enter the field.
