Motility

Definition in words

 Ability of an organism to move independently compared to the movement ability of a reference organism

Systematic terms

 Motility 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 1Value 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

Reproduction and Fertility

 Example 1
Generic abbreviated form NPU18194 Sem—Spermatozoa; motility(proc.) = ?
Full form with a result NPU18194 Semen—Spermatozoa; motility(procedure) = 3
Abbreviated form with a result NPU18194 Sem—Spermatozoa; motility(proc.) = 3
Written expression The motility of Spermatozoa in Mr. Smith’s Semen is [3]. The measurement is performed according to procedure defined by the laboratory.
Example 2
Generic abbreviated form NPU54019 Sem—Spermatozoa; motility(Direct swim-up; proc.) = ?
Full form with a result NPU54019 Semen—Spermatozoa; motility(Direct swim-up; procedure) = Low
Abbreviated form with a result NPU54019 Sem—Spermatozoa; motility(Direct swim-up; proc.) = Low
Written expression The motility of Spermatozoa in Mr. Smith’s Semen is [Low]. The measurement is performed according to direct swim-up procedure defined by the laboratory.
