Puncture of a vein to remove samples of blood for analysis is called?

Explanation:
Drawing blood from a vein for analysis is phlebotomy. This term refers to the process of obtaining a blood sample by puncturing a vein, typically in the arm, so it can be analyzed in the lab. The other terms describe unrelated procedures: paracentesis removes fluid from a body cavity (like the abdomen); a PET scan is an imaging test using radioactive tracers; a proctosigmoidoscopy is an endoscopic exam of the rectum and sigmoid colon.
