Definition: The structured numeric data type is used to unambiguously express numeric clinical results along with qualifications. This enables receiving systems to store the components separately, and facilitates the use of numeric database queries. The corresponding sets of values indicated with the and components are intended to be the authoritative and complete set of values. If additional values are needed for the and components, they should be submitted to HL7 for inclusion in the Standard.

If and are both non-null, then the separator/suffix must be non-null. If the separator is "-", the data range is inclusive; e.g., - defines a range of numbers x, such that: <=x<= .

18.3.70.1 Comparator (ST) (2A.3.71.0)

Definition: Defined as greater than, less than, greater than or equal, less than or equal, equal, and not equal, respectively ( ">" or "<" or ">=" or "<=" or "=" or "<>").

If this component is not valued, it defaults to equal ("=").

18.3.70.2 Num1 (NM) (2A.3.71.1)

Definition: A number.

18.3.70.3 Separator/Suffix (ST) (2A.3.71.2)

Definition: "-" or "+" or "/" or ":"

Examples:

|^100^-^200|

(ratio of 1 to 128, e.g., the results of a serological test)

18.3.70.4 Num2 (NM) (2A.3.71.3)

Definition: A number or null depending on the measurement.
