Summary

Mandatory: 1 element(4 nested mandatory elements)
Must-Support: 1 element

Slices

This structure defines the following Slices:

  • The element 1 is sliced based on the value of Observation.meta.security

 

Other representations of profile: CSV, Excel, Schematron

Notes:

Notes

Value[x]

Observation values can be reported in many forms. CIBMTR currently supports only two:

  • valueQuantity
  • valueCodeableConcept

CIBMTR does NOT support any other value types (e.g., valueString is not currently supported)

Special rules:

  • For CMV LOINC codes that use ValueQuantity, it MUST be accompanied with a referenceRange
