Medical Technology is the new catch-all for what we used to call Laboratory technology. It's a great field for anyone with a love of science. There are many different levels in the field, including graduate degrees. They work in a variety of settings - from forensic analysis to surgical suites and everything in between. Like every other career field, more education = more $, but also there are fewer jobs at the higher levels.
Hint- if you aren't able to deal with microbiology or chemistry, this field is probably not for you.
