The duties of a phlebotomy supervisor revolve around overseeing a staff of phlebotomists. Phlebotomists are medical specialists who draw blood samples. As a phlebotomy supervisor, you monitor activity in the laboratory, schedule staff, organize inventory supplies and equipment, and liaise with other professionals in the clinic, donation center, or hospital. You also act as a link between the lab employees and management. Your responsibilities may include documentation duties such as verifying the identity and medical history of donors or patients and ensuring samples are correctly labeled.
