Presence

by | Feb 4, 2020 | List of kinds-of-property, Kind-of-quantity

Presence

Definition in words

 Something that is existing or occuring

Systematic terms

 Presence of component B in system 1

Result type

 Ordinal scale
  • Value set is ranked accoding to magnitude
  • The value set and the limit of the value set are defined by the laboratory
  • The value set can be either numerical values or words.

Example 1

Value set={none < some < high < very high}

Example 2

Value set={low < normal< high }

Example 3

Value set={0 < 1 < 2}

Example 4

Value set={negative < positive}

Example 5

Value set={+ < ++ < +++}
  • Algebraic operations are not allowed (Ref. 2, 1.26)
  • Possible comparison of value sets  (a<b, a=b or a>b).

Unit

 None

Special rule(s) in the NPU syntax

“Procedure” is stated in the specification to the kind-of-property in the NPU definition.

“Procedure” indicates that the measurement procedure must be stated somewhere else than the NPU code and there may be difficulties in comparing values for the same NPU code.

Examples

Clinical Chemistry

 Example 1
Generic abbreviated form NPU14908 Pt—Stomach pain; presence(proc.) = ?
Full form with a result NPU14908 Patient—Stomach pain; presence(procedure) = Absent
Abbreviated form with a result NPU14908 Pt—Stomach pain; presence(proc.) = Absent

Full form with a result NPU18224 Patient—Fast; presence(procedure) = Present
Abbreviated form with a result NPU18224 Pt—Fast; presence(proc.) = ?
Written expression The presence of Mr. Smith’s fast is [present]. The measurement is performed according to procedure defined by the laboratory.
Example 3
Generic abbreviated form NPU18236 Pt—Borborygmi; presence(proc.) = ?
Full form with a result NPU18236 Patient—Borborygmi; presence(procedure) = Absent
Abbreviated form with a result NPU18236 Pt—Borborygmi; presence(proc.) = Absent
Written expression The presence of Mr. Smith’ Borborygmi is [absent]. The measurement is performed according to procedure defined by the laboratory.
Example 4
Generic abbreviated form NPU18240 Pt—Diarrhoea; presence(proc.) = ?
Full form with a result NPU18240 Patient—Diarrhoea; presence(procedure) = Present
Abbreviated form with a result NPU18240 Pt—Diarrhoea; presence(proc.) = Present
Written expression The presence of Mr. Smith’s Diarrhoea is [present]. The measurement is performed according to procedure defined by the laboratory.
