Concepts

This case-sensitive code system `http://terminology.hl7.org/v2plusvocab/CodeSystem/exclusiveTest` defines the following codes:

Code | Display | Definition | version introduced | comment, to suppress IG-publisher warning, to be replaced with standard later | modified
D | In some cases, this test should be only exclusively with like tests (examples are cyto or pathology) | In some cases, this test should be only exclusively with like tests (examples are cyto or pathology) | 2.8 | When D is specified for this field, using field OM1-49 determines how tests must be grouped together. Tests within the same Diagnostic Service Sector may be on the same requisition, and therefore in the same message | 2015-07-13
N | This test can be included with any number of other tests | This test can be included with any number of other tests | 2.8 | Default -.will be assumed when this field is empty | 2015-07-13
Y | This test should be exclusive | This test should be exclusive | 2.8 |  | 2015-07-13
