Identifies the type of observation that is made about a specimen that may affect its processing, analysis or further result interpretation

Logical Definition (CLD)

This value set includes codes based on the following rules:

This value set excludes codes based on the following rules:



Expansion based on codesystem ActCode v9.0.0 (CodeSystem)

This value set contains 17 concepts.


Describes the artificial blood identifier that is associated with the specimen.


An observation that reports the dilution of a sample.

  AUTO-HIGHhttp://terminology.hl7.org/CodeSystem/v3-ActCodeAuto-High Dilution

The dilution of a sample performed by automated equipment. The value is specified by the equipment

  AUTO-LOWhttp://terminology.hl7.org/CodeSystem/v3-ActCodeAuto-Low Dilution

The dilution of a sample performed by automated equipment. The value is specified by the equipment


The dilution of the specimen made prior to being loaded onto analytical equipment

  RERUNhttp://terminology.hl7.org/CodeSystem/v3-ActCodeRerun Dilution

The value of the dilution of a sample after it had been analyzed at a prior dilution value


Domain provides codes that qualify the ActLabObsEnvfctsCode domain. (Environmental Factors)


An observation that relates to factors that may potentially cause interference with the observation


The Fibrin Index of the specimen. In the case of only differentiating between Absent and Present, recommend using 0 and 1


An observation of the hemolysis index of the specimen in g/L


An observation that describes the icterus index of the specimen. It is recommended to use mMol/L of bilirubin


An observation used to describe the Lipemia Index of the specimen. It is recommended to use the optical turbidity at 600 nm (in absorbance units).


An observation that reports the volume of a sample.

  AVAILABLEhttp://terminology.hl7.org/CodeSystem/v3-ActCodeAvailable Volume

The available quantity of specimen. This is the current quantity minus any planned consumption (e.g., tests that are planned)

  CONSUMPTIONhttp://terminology.hl7.org/CodeSystem/v3-ActCodeConsumption Volume

The quantity of specimen that is used each time the equipment uses this substance

  CURRENThttp://terminology.hl7.org/CodeSystem/v3-ActCodeCurrent Volume

The current quantity of the specimen, i.e., initial quantity minus what has been actually used.

  INITIALhttp://terminology.hl7.org/CodeSystem/v3-ActCodeInitial Volume

The initial quantity of the specimen in inventory

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
