Can sone eplain the difference between a MA, Clinical MA an Adminstrative MA

I think I know, but would like some clarification before I enroll in an allied health program.
I think it is the MA and MAA that needs clarification.
Clinical MA works with injection, sticks, EKG, vitals, right?

I am looking to be a front desk person, per-cert, insurance verifications with MAYBE, the possibility of phlebotomy, but I think my heart belongs at the front desk.

Thank you so much and I hope I did not post this in the wrong area.
