6 Clinician Validation of the LIM LIM ID LIM Name LIM Cardin ality LIM Definition LIM Example (for Exchange) LIM Example (for Display) Laboratory Test Item 1 A class describing the laboratory test that was performed. Test Name1 The name of the laboratory test within a panel of tests. ("xxx", "LDH measurement") ("xxx", "Blood sodium measurement") "LDH measurement" "Blood sodium measurement" Sequence Number 0..1 A number that identifies and sequences this laboratory test item within a given panel. "1" "2" Additional Description 0..1 A descriptor used in combination with the Test Name to fully define the description of the laboratory test.

10 IsoSemantic Models – Compositional Grammar Problem Diagnosis = $ProblemDiagnosisName: |associated_finding|= ( |clinical_finding|: |finding_site|=($BodySite: |laterality|=$Laterality), |severity|=$Severity), |finding_context|=$FindingContext

11 IsoSemantic Models – Equivalence Testing Problem Diagnosis = $ProblemDiagnosisName: |associated finding| = ( |Clinical Finding|: | finding site | = ($BodySite: |laterality| = $Laterality), | severity| = $Severity), | finding context | = $FindingContext GP Problem Diagnosis = |Cancer| : |associated finding| = ( |Clinical Finding| : | finding site | = |Lung|), | finding context | = |Suspected| Polyclinic Problem Diagnosis = |Suspected cancer|: |associated finding| = ( |Clinical Finding|: | finding site | = |Lung|) RH Problem Diagnosis = |Suspected lung cancer|
