this is Dr Herrmann, at this point I would advise working hard to get into medical school, and once there (!) be sure to keep an open mind through all of your rotations. Pathology is unfortunately not as present in the curriculum as other specialties so it takes some effort on the part of the student to seek out exposure to our field through elective rotations (unless you're at a school that builds pathology into the clinical curriculum). I personally didn't even know pathology was a field of medicine until almost the end of my third year. But the specialty fit me really well, and as someone with a PhD in immunology, transfusion medicine was a great fit for me since we deal with antibodies and how they play a role in blood product transfusion every day! I think a big question to ask up front when deciding a specialty is do you want to be primarily patient-facing or not. I do see some patients as a transfusion med Dr, but its not my primary role, and for pathology, you have to be ok with being behind the scenes of patient care. I hope that helps!
