HL7 published code system of concepts that describe categories of an underlying kind of property represented by an observation. These are intended to distinguish 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. These defined categories are derived from the approach described in 1995 edition of the IUPAC Silver Book. These distinctions are used in IUPAC and LOINC standard codes. Needs review by OO and HTA to determined if this is a value set built on LOINC part codes or some other external vocabulary.
