CE_0254
CE bound to table 255
Composite
Definitions: This optional attribute describes the underlying kind of property represented by this observation. This attribute distinguishes concentrations from total amounts, molar concentrations from mass concentrations, partial pressures from colors, and so forth. These are discussed more fully in the LOINC Users' Manual.[1] They are derived from the approach described in 1995 edition of the IUPAC Silver Book.[2] These distinctions are used in IUPAC and LOINC standard codes. Defined categories are listed in HL7 table 0254 - Kind of quantity.
The distinctions of true quantities in this table are based primarily on dimensional analyses. The table contains a number of "families," those related to simple counts (number, number concentration, etc.), to mass (mass, mass concentration, etc.), to enzyme activity (catalytic content, catalytic concentration, etc.), and molar or equivalents (substance content, substance concentration).
