administration for medications. As a pharmacy technician student
studying for the PTCB or ExCPT exam, it's highly recommended to memorize
all of the abbreviations your training program covers. After you pass the pharmacy tech test and start your career, knowing all of these sig codes will be a vital part of your competency.
Q. Is this list all of the abbreviations used in medicine?
A. Not exactly.
is a custom list that's been customized for pharmacy tech students
studying for the PTCB exam. It was carefully decided upon with regards to not overload students with info not needed for the PTCB. If you're in a program, you may get a bigger list and want to adhere to it.
