The phlebotomist then locates a vein and inserts a needle, a process called âvenipuncture.â Phlebotomists can also sample blood through skin puncture, such as pricking a finger to test a patientâs blood sugar or determine blood type. The phlebotomist must ensure that all equipment is properly sanitized before it is used to collect blood. Accurate labeling, proper storage and careful transport are also key responsibilities. Misidentification or contamination of a blood sample can have serious consequences, because medical professionals rely on blood test results to diagnose patients and monitor treatment progress.
