Data model for digital representation of laboratory test results as proposed by SHIELD
| Test data element | Standardized ontology | |
|---|---|---|
| Test information | Test ordered | LOINC to identify the test ordered |
| Test performed | LOINC to identify the test performed | |
| Specimen information | Specimen type | SNOMED CT at minimum |
| Specimen source | SNOMED CT | |
| Specimen collection method | SNOMED CT | |
| Results | Quantitative | Needs to include units of measure with UCUM preferred |
| Qualitative | SNOMED CT | |
| Methodology | Test kit identification | Device identifier |
| Instrument identification | Device identifier | |
Abbreviations: SHIELD, Systemic Harmonization and Interoperability Enhancement for Laboratory Data; LOINC, Logical Observation Identifiers Names and Codes; SOMED CT, Systematized Nomenclature of Medicine – Clinical Terms; UCUM, Unified Codes for Units of Measure.
