The job of a phlebotomist starts when a blood test is ordered. The blood is drawn, labeled and sent for testing. Though it is a fairly routine procedure, the phlebotomist should also be ready to deal with any unexpected occurrences, and be able to keep the patient calm. Phlebotomists work in labs, buses at blood drives or in testing sites. Sometimes they travel to collect blood samples or transport them back to the lab. These lab technicians must also be familiar and adept at working with infectious samples, and know how to protect themselves and others accordingly. They must be familiar with all the equipment at each site. Most start working part time and build up their hours.
