Phlebotomy is the process of making a puncture in a vein usually in the arm, with a cannula, for the purpose of drawing blood. The procedure itself is known as venipuncture. Phlebotomy technician programs – which teach you how to draw blood and work with patients throughout this process – can prepare you for a job as a phlebotomist in less than one year (depending on the individual student). Also, the job outlook is strong! The demand for phlebotomists is expected to grow 25% between 2016 and 2026, according to the United States Bureau of Labor Statistics.
