Arbitrary viscosity (arb.viscosity)

Abbreviation

Arb.viscosity

Definition in words

Arbitrary viscosity of component B in system 1 compared with arbitrary viscosity of component B in a reference system

Note: The reference system is defined by the laboratory

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 values (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 NPU58256 Synf(spec.)—Synovial fluid; arb.viscosity(proc.) = ?
Full form with a result NPU58256 Synovial fluid(specification)—Synovial fluid; arbitrary viscosity(procedure) = high
Abbreviated form with a result NPU58256 Synf(spec.)—Synovial fluid; arb.viscosity(proc.) = high
Written expression The arbitrary viscosity of synovial fluid from Mr. Smith’s right knee is [high] compared with the arbitrary viscosity of synovial fluid of a reference system. The measurement is performed according to a procedure defined by the laboratory.
Notes
  1. The reference system is defined by the laboratory.
  2. “High” is a value according to a value set defined by the laboratory.
  3. “Right knee” is specified by the laboratory in a medical record.

Example 2
Generic abbreviated form NPU01525 CerMu—Cervical mucus; arb.viscosity(proc.) = ?
Full form with a result NPU01525 Cervical Mucus—Cervical mucus; arbitrary viscosity(procedure) = 2
Abbreviated form with a result NPU01525 CerMu—Cervical mucus; arb.viscosity(proc.) = 2
Written expression The arbitrary viscosity of cervical mucus from Mrs. Smith is [2] compared with the arbitrary viscosity of synovial fluid of a reference system. The measurement is performed according to a procedure defined by the laboratory.
Notes
  1. The reference system is defined by the laboratory.
  2. “2” is a value according to a value set defined by the laboratory.
