A back translation is the translation of a target document back to the original source language. Back translations are done by subject matter experts without access to the original source document. The back translation will help to identify any potential ambiguities or sensitive details that may have been overlooked or misunderstood in the translation. A back translation is sometimes legally necessary. For example, Institutional Review Boards (IRBs) and ethics committees may require a back translation and certificate of accuracy for translations of highly sensitive or high risk information such as pharmaceutical inserts or clinical trials materials.
