Word of the Day

international unit

ABBR: I.U. An internationally accepted amount of a substance. Usually this form of expressing quantity is used for fat-soluble vitamins and some hormones, enzymes, and biologicals such as vaccines. These units are defined by the International Conference for Unification of Formulae.
The abbreviation “I.U.” should not be used in the medical record. It is easily mistaken for other symbols or abbreviations; e.g., for the abbreviation for intravenous, “IV.”
