Phlebotomists are medical professionals who draw blood and collect other samples for testing or donation. The samples are then sent to a medical lab for analysis; physicians use the results to diagnose conditions such as chronic disease, high cholesterol, and diabetes. Due to the high risk of spreading infection when handling blood and other tissue, Phlebotomists must ensure they wear gloves and that all their equipment is sterile. As a Phlebotomist, you need to cross-check all your labels to make sure they are accurate and match the patient. You may work with patients of many different ages—from newborns to elderly patients—so you should be friendly and learn how to interact well with all types of people.
