Comment

APHL comment to update and clarify the definition of Test Name

The current definiton does not differentiate if this is the test that was ordered (in v2 tracked in OBR-4), or the test that was performed (in v2 reported in OBX-3, in C-CDA and FHIR in observation.code). From a result re-use perspective the test of interest to track is the performed test - this is a subtype of the proposed element Observation Code (https://www.healthit.gov/isa/taxonomy/term/1406/level-2), so if that is added clarification between when to use which would be needed. This is a CLIA required element. The vocabulary binding should indicate that the most recent version of LOINC should be used (currently 2.71) and that the version listed is merely applicable version at the time of publication.  

Specifying LOINC lab terms

The Regenstrief LOINC team recommends adding “Type 1 (Laboratory) terms” to the Applicable Standard(s) text for the Tests row. LOINC contains 4 different types of terms, and type 1 encompasses the laboratory domain.
