Indiana School of Phlebotomy's Phlebotomy Program provides the student with skills and training in order to succeed as a phlebotomist. This course contains 6-weeks of lecture, discussion, and practical instruction in the lab, followed by a 40-hour clinical externship at a local patient service center, hospital or clinic. The hours of the externship are site-specific but are usually done over the space of one week, Monday through Friday.
