So you want to just take a paid internship and be a pharmacist? How about a doctor?
There's a lot of very specific knowledge necessary to become an MT. A new grad needs to know how to read blood differentials, analyze urine, do microbiology, proper QC on hospital lab instruments etc. Not knowing this could put patients at risk.
You need to enroll in an entirely different academic program. The program requires you to take classes and enroll in a hospital internship. This can be hospital based or university based but its really the same. And most good hospitals will require you to pass the ASCP afterwards (some of the better paying states even require it as a condition of employment). The good news is once you do all the prereqs you can complete it in a year (mind you thats with no breaks) and get right to work. There's probably more job openings available to MTs in south dakota than chemists however, and probably better paying as well.
May also want to look into pathologist assistant programs if you like lab work. Much more expensive schooling but better paying as well.
