What does AU represent in medical abbreviations?

The abbreviation "AU" in medical terminology stands for "auris unitas," which translates to "both ears." This term is used in situations where treatment or examination pertains to both ears simultaneously, ensuring that healthcare providers are clear about addressing both sides when prescribing medications or performing assessments related to auditory health. This is particularly relevant in contexts such as audiology or when administering eardrops.

In contrast, the other options refer to specific locations for treatment or examination. "Both eyes" is represented by "OU," while "right eye" is indicated by "OD" and "left eye" is indicated by "OS." Understanding these abbreviations is essential for effective communication in medical environments, ensuring that patients receive appropriate care tailored to their needs.
