Understanding What Is Phlebotomy
Definition of phlebotomy
Phlebotomy is the process of making a controlled puncture in a vein with a needle to draw blood for laboratory testing, transfusions, blood donation, or research purposes. The term originates from the Greek words “phlebo,” meaning vein, and “tomia,” meaning incision or cutting. despite the literal meaning, in medical practice, it typically involves puncturing a vein with a sterile needle for blood collection.
The Difference Between Phlebotomy and Vein Puncture
