Artifacts Summary

This page provides a list of the FHIR artifacts defined as part of this implementation guide.

Structures: Abstract Profiles

These are profiles on resources or data types that describe patterns used by other profiles, but cannot be instantiated directly. I.e. instances can conform to profiles based on these abstract profiles, but do not declare conformance to the abstract profiles themselves.

Standard Laboratory Observation Base profile

An abstract base profile on which other sub-types will be built.

Structures: Resource Profiles

These define constraints on FHIR resources for systems conforming to this implementation guide.

Standard Lab Obs Coded

The base profile for all lab tests with coded results (excluding ordinal).

Standard Lab Obs Document

A base profile for all LOINC lab tests that have an attached document or structured text as the result.

Standard Lab Obs Narrative

The base profile for all LOINC lab tests that have textual results in a string format.

Standard Lab Obs Ordinal

The base profile for all LOINC lab tests that have ordinal results.

Standard Lab Obs Quantitative

An abstract laboratory observation profile for quantitative types of lab tests.

Standard Lab Obs Titer

The base profile for all LOINC lab tests that have titer results.

Structures: Extension Definitions

These define constraints on FHIR data types for systems conforming to this implementation guide.

Attached Document

An extension for attaching a document to an observation

Document URL

An extension that records the URL for an attached document.

Lab Document extension

This extension is to create a means by which a laboratory test that has been reported using an attached document may be done.

Reference Range Nominal

This is an extension for the Reference Range element in Observation and is used to capture coded types of reference ranges.

Terminology: Value Sets

These define sets of codes used by systems conforming to this implementation guide.

Abnmormal Interpretation value set

A set of Snomed CT codes that describe the abnormality of a lab test result.

Abnormal Interpretation Numeric Nominal value set

A set of Snomed CT terms that describe the abnormality of numeric laboratory tests, when applicable.

LOINC Document class value set

A set of LOINC codes that are used for lab tests that are reported using attachments (documents, reports, etc.)

Lab Result Code value set

A set of LOINC codes that describe laboratory tests.

Null Flavor value set

A set of Snomed CT codes that describe when a test result would not have a value.

Ordinal Value Code value set

A set of Snomed CT codes that are used to describe lab test results that are of an ordinal nature.

Standard Coded Lab Observation Code value set

A set of LOINC codes that describe lab tests that are nominal.

Standard Coded Ordinal Lab Observation Code value set

A set of LOINC codes that describe lab tests that are nominal.

Standard Lab Obs Narrative value set

A set of LOINC codes that are used for lab tests with tex-based results.

Standard Lab Obs Quantitative Code value set

A set of LOINC codes that are used to identify quantitative types of lab tests.

Titer Lab Codes value set

A set of LOINC codes used to identify titer laboratory tests.

Units of Measure value set

A set of codes from the UCUM codes system.
