Using a study guide for phlebotomy can be very beneficial for many people, for quite a few reasons. The absolute positive benefit that outweighs any other benefit is, the phlebotomy student will always have a constant reference at their fingertips for any unanswered questions that arise in the classroom and lab discussions. A general study guide is loaded with information anywhere from definitions, to games and practice tests. The overall biggest attribute to using a study guide is the availability of practice test questions that mimic test questions on the NCPT Exam. This attribute of a study guide alone, makes the study quite well worth the money spent.
