A high school graduate or college student could take a course at a local technical or vocational school and learn phlebotomy. If you're not trained or qualified in any other nursing skills, compensation may be limited, (probably around $7.00-9.00 per hour, approximately).
Many professionals who plan to become a nurse or a doctor often start out by working in a medical office or hospital as a phlebotomist. Because phlebotomy entails a fairly short training period, and because phlebotomist jobs are relatively easy to find and obtain, phlebotomy is a great way for someone to try out the medical profession. Jobs for phlebotomists are available at hospitals, medical offices, and clinics. Additionally, if you already work in a medical office or hospital in another setting, you may be able to obtain on-the-job training to learn how to draw blood without having to take a course.
