Some of the other posters have mentioned this, but I will too. I work in a hospital where tech's are allowed to draw blood. They trained me in their outpatient lab and on the job, for free. If you know where you are planning on working you can call and ask if they allow the techs to draw blood and if so, what kind of training is provided. If they don't allow it, you might not be able to draw blood anyway, even with a phlebotomy certificate, unless you work as a phlebotomist.
