measurand

quantity intended to be measured

Note 1

The specification of a measurand in laboratory medicine requires knowledge of the kind of quantity (e.g., mass concentration), a description of the matrix carrying the quantity (e.g., blood plasma), and the chemical entities involved (e.g., the analyte).

Note 2

The measurand can be a biological activity.

Note 3

See 3.3 for other examples of IVD measurands.

Note 4

In chemistry, “analyte”, or the name of a substance or compound, are terms sometimes used for “measurand”. This usage is erroneous because these terms do not refer to quantities.
