Morphology

Definition in words

Structure and shape of organisms

Systematic terms

Morphology of component B in system 1
Narrative description
  • Value sets are structural sentences with two or more values
  • Algebraic operations are not allowed
  • Possible comparison of value sets (a=b; a≠b)

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.

Laboratory field

Examples

Clinical Chemistry

 

Example 1
Generic abbreviated form NPU04221 B—Erythrocytes; morphology(proc.) = ?
Full form with a result NPU04221 Blood—Erythrocytes; morphology(procedure) = anisocytosis, hypochromia and microcytosis
Abbreviated form with a result NPU04221 B—Erythrocytes; morphology(proc.) = anisocytosis, hypochromia and microcytosis
Written expression The morphology of Erythrocytes in Mr. Smith’s Blood is [anisocytosis, hypochromia and microcytosis]. The measurement is performed according to procedure defined by the laboratory.

Clinical Microbiology

Example 2
Generic abbreviated form NPU58096 U—Bacterium; morphology(proc.) = ?
Full form with a result NPU58096 Urine—Bacterium; morphology(procedure) = Gram-negative, rodchape, coliformed bacterium
Abbreviated form with a result NPU58096 U—Bacterium; morphology(proc.) = Gram-negative, rodchape, coliformed bacterium
Written expression The morphology of Bacterium in Mrs. Smith’s Urine is [Gram-negative, rodchape, coliformed bacterium]. The measurement is performed according to procedure defined by the laboratory.

Reproduction and Fertility

Example 3
Generic abbreviated form NPU58014 Pt—Oocyte; morphology(proc.) = ?
Full form with a result NPU58014 Patient—Oocyte; morphology(procedure) = clear, moderately granular cytoplasm, small perivitelline space, and a clear to colourless zona pellucida
Abbreviated form with a result NPU58014 Pt—Oocyte; morphology(proc.) = clear, moderately granular cytoplasm, small perivitelline space, and a clear to colourless zona pellucida
Written expression The morphology of Mrs. Smith’s Oocyte is [clear, moderately granular cytoplasm, small perivitelline space, and a clear to colourless zona pellucida]. The measurement is performed according to procedure defined by the laboratory.
