Feature common to equivalent individual nominal properties.
Examples: - "Yellow" is a nominal property value for a nominal property of the kind-of-nominal-property "colour" of a given Urine as system. There is no separate component.
- "*1/*3" is a nominal property value for a nominal property of the kind-of-nominal-property "sequence variation" of the CYP2D6 gene in a given "DNA" as system. The allele "*1" is related to normal enzyme activity while the allele "*3" is related to decreased enzyme activity.
- The species \(Mycobacterium\ tuberculosis\) is a nominal property value for a nominal property of the kind-of-nominal-property taxon of the component \(Mycobacterium\) in a given "Expectoration" as system. Infectious diseases might be caused by several different species of \(Mycobacterium\). The species can be examined in a sample from an expectoration.
- "Oval" is a nominal property value for a nominal property with of kind-of-nominal-property "shape" of the component "Leukocyte nucleus" in a given Blood as system. This shape is typical of immature forms of monocytes, such as promonocytes,
Notes: - Nominal property values can be words, alphanumerical codes, symbols, etc, but cannot enter into algebraic equations and is not related to a quantity dimension or a measurement unit.
- A nominal property value can consist of a set of items.
Example: The colours of the national flag of Switzerland are red and white. - The term "nominal quantity value" and its short form "nominal value" are used to indicate a concept concerning rounded or approximate quantity values. The term "nominal indication interval" is used to indicate a concept concerning rounded or approximate extreme indications.
