what's Phlebotomy?

Phlebotomy (from the Greek words phlebo-, meaning "pertaining to a blood vessel", and -tomy, meaning "to make an incision") is the process of making an incision in a vein with a needle. The procedure itself is known as a venipuncture. A person who performs phlebotomy is called a "phlebotomist", although doctors, nurses, medical laboratory scientists and others do portions of phlebotomy procedures in many countries
