I'm not going to argue about which is better if you don't get in, but the fact is that medical schools tend to accept a higher percentage of traditional majors. By traditional I don't mean traditional premed (bio, biochem, chem, etc.), I mean traditional in the more broad sense (including liberal arts, history, engineering, physics, math, business, etc.). At least where I go to school medical lab science is in the nursing school, and looking at most of the classes, it seems very technical. Most of the courses revolve around working in a lab. Students there don't take a broad array of classes like in the other "traditional" programs. That's why I think they don't do as well in terms of acceptances. Personally I wouldn't major in medical lab science unless that's really what I wanted to do with my life. Too technical for me. It's almost like a certificate program you might find at a community college.
