At its core, phlebotomy is the process of drawing blood from a patient’s vein for testing, donation, or medical purposes. derived from Greek words “phlebos” (vein) and “tome” (cutting), phlebotomy essentially means “cutting into a vein.” despite its historical roots, modern phlebotomy is a highly regulated and skillful procedure essential for diagnosing diseases, monitoring health, and supporting treatments.
What Is Phlebotomy? Definition and Overview
In simple terms, phlebotomy is the process of collecting blood samples using sterile techniques to minimize infection risk. it involves various steps such as patient identification, selecting the appropriate veins, and ensuring minimal discomfort during collection. The procedure is performed by trained professionals called phlebotomists.

Types of Blood collection in Phlebotomy
Depending on the purpose, blood collection can be categorized into:
- Venipuncture: Drawing blood from a vein, most common method
- Capillary Puncture: Using a lancet to collect blood from fingertip or heel, frequently enough used for glucose testing
- Arterial Puncture: Less common, used for arterial blood gases and other specific tests
