reference set membership test

reference set membership test

A test to determine whether a specified SNOMED CT component is a member of a specified reference set.

Notes

• A component is a member of a reference set if at least one active row in that reference set has a referenceComponentId "Reference term: referenceComponentId (field)") that matches the __ identifier of that component. Otherwise, a component is not a member of that reference set.

• Reference set membership tests may be used to filter searches or as part of a expression constraint or query.

• In an expression constraint a reference set membership test is represented by the symbol** ^** followed by a concept id identifying the reference set.
