Phlebotomy involves drawing blood from patients for laboratory testing. A requisition form with proper patient information must accompany each blood sample submitted to ensure accurate processing. Blood is typically collected from the heel of newborn babies and infants. The responsibilities of a phlebotomist include explaining procedures to patients, updating records, sterilizing equipment, taking vital signs, and sending urine samples for analysis. Phlebotomists can expect to earn a salary for their work drawing and handling blood samples.
