NPU Terminology

NPU terminology (pronounced en-pew terminology), also known as Nomenclature for Properties and Units, is a system used in the field of clinical biochemistry to unambiguously describe the results of measurements. The etymology of the term "NPU" is derived from the initial letters of the words 'Nomenclature', 'Properties', and 'Units'.

Definition

NPU terminology is a systematic naming convention for properties and units in the field of clinical biochemistry. It is used to ensure consistency and clarity in the communication of clinical laboratory results. The terminology is based on the principles of metrology, the science of measurement.

Structure

The structure of an NPU code consists of three parts: the component (what is measured), the kind-of-property (what characteristic is measured), and the unit (how the measurement is expressed). Each part is separated by a semicolon.

Usage

NPU terminology is used globally in the field of clinical biochemistry. It is endorsed by the IFCLM and the BIPM.
