[1] International (IU) and United States Pharmacopeia (USP) units are defined in terms of comparison to a physical reference preparation; the mass or volume that constitutes one ‘unit’ varies based on which substance is being measured and the variance is based on the biological activity or effect. IU and USP units are used to quantify vitamins, hormones, some medications, vaccines, blood products, and other biologically active substances. Although the meaning of IU and USP units differs from substance to substance, comparisons to the underlying WHO or USP reference preparation can be made, facilitating interoperability across multiple institutions. In contrast, arbitrary units [arb’U] contain an arbitrary scale factor and preclude any meaningful comparison across multiple institutions (although comparability within a given institution may be possible).
