As a contract phlebotomist, your responsibilities are to travel to a clinic or hospital and help get a sample of blood from a patient. Your duties usually involve using a needle to draw blood from a vein to perform a test or transfusion, but in rare cases, you may use other techniques to meet the unique medical needs of a patient. After collecting the blood, you help prepare the sample to be transferred to a laboratory for tests. In this contractor role, you serve local facilities on an assignment-basis for a specified time.
