What do the letters and numbers on prescriptions and doctors notes mean?
Have you ever wondered why you can't read the doctor's note or the letters and numbers on a prescription? Health care professionals often quickly scribble notes with important medical information that they would like a patient to reference in regard to the type of current, or recently diagnosed disease, syndrome, or other health condition(s). Have you ever see the doctor's notes in your medical record and found peculiar abbreviations and jargon? Do you wonder what the letters and numbers mean on your prescriptions or other items related to a disease, syndrome, or disorder?
Doctors and other health care professionals commonly use a list of abbreviations, acronyms, and other medical terminology as a reference to rapidly search and accurately record information about, and give instructions to their patients. There is no standard or approved list used by health care professionals to search for medical acronyms or abbreviations. Therefore, it is important to understand the context in which the abbreviation or term has been used.

This is a short list of common abbreviations you may have seen on a doctor's notepad; a prescription drug package or bottle; lab or other test results; or in your doctor's notes.
