CodeSystemDisplayDefinitionstatus
  Lhttp://terminology.hl7.org/CodeSystem/v3-ObservationInterpretationLow

The result for a quantitative observation is below the lower limit of the reference range (as defined for the respective test procedure).

Synonym: Below low normal

  L<http://terminology.hl7.org/CodeSystem/v3-ObservationInterpretationSignificantly low

A test result that is significantly lower than the reference (normal) or therapeutic interval, but has not reached the critically low value and might need special attention, as defined by the laboratory or the clinician.

[Note: This level is situated between 'L' and 'LL'.]

Deprecation Comment: The code 'L<' is being deprecated in order to align with the use of the code 'LU' for "Very low" in V2 Table 0078 "Interpretation Codes".

[Note: The use of code 'L<' is non-preferred, as this code is deprecated and on track to be retired; use code 'LU' instead.

deprecated
  LLhttp://terminology.hl7.org/CodeSystem/v3-ObservationInterpretationCritical low

The result for a quantitative observation is below a reference level at which immediate action should be considered for patient safety (as defined for the respective test procedure).

Synonym: Below lower panic limits.

  LUhttp://terminology.hl7.org/CodeSystem/v3-ObservationInterpretationSignificantly low

A test result that is significantly lower than the reference (normal) or therapeutic interval, but has not reached the critically low value and might need special attention, as defined by the laboratory or the clinician.


Explanation of the columns that may appear on this page:

Level A few code lists that FHIR defines are hierarchical - each code is assigned a level. In this scheme, some codes are under other codes, and imply that the code they are under also applies
System The source of the definition of the code (when the value set draws in codes defined elsewhere)
Code The code (used as the code in the resource instance)
Display The display (used in the display element of a Coding). If there is no display, implementers should not simply display the code, but map the concept into their application
Definition An explanation of the meaning of the concept
Comments Additional notes about how to use the code
