Job Certifications? (Please move if in wrong section)

Sorry, I’m still not sure of the forum and where stuff goes so excuse me if this is in the wrong section, but I have a quick question:

Can you take the certification test for MLT and/or MA (medical assistant ) certification with an associate’s in Life Sciences? I know my A.S. is virtually useless in the science field, but I’m working on my bachelor’s as we speak and working on getting into medical school~

I’m currently working in a factory which the pay is good, but I’m growing tired of the job. Also it’s graveyard shift so the hours are taking a toll on my mind a bit. It’ll be nice to do something with my A.S.
I live in Pennsylvania if that helps. I know for PA, to be a MA, you only need a HS diploma to take the certification test. However, for MLT I get varying answers online. A point to the right direction would be lovely and any advice as well.
I have lab experience. I just don’t want to waste money on the tests for potential employers to say they won’t accept it without experience. Thanks!
