This value set contains 12 concepts

System | Code | Display (en) | Definition | JSON | XML
`http://terminology.hl7.org/v2plusvocab/CodeSystem/specimenRole` | B | Blind Sample | Used to test the validity of the measurement process, where the composition of the sample is unknown except to the person submitting it. |  |
`http://terminology.hl7.org/v2plusvocab/CodeSystem/specimenRole` | C | Calibrator | Used for initial setting of calibration of the instrument. |  |
`http://terminology.hl7.org/v2plusvocab/CodeSystem/specimenRole` | E | Electronic QC | Used with manufactured reference providing signals that simulate QC results |  |
`http://terminology.hl7.org/v2plusvocab/CodeSystem/specimenRole` | F | Filler Organization Proficiency | Specimen used for testing proficiency of the organization performing the testing (Filler). |  |
`http://terminology.hl7.org/v2plusvocab/CodeSystem/specimenRole` | G | Group | Used when solid specimens consist of multiple individual elements that are not individually identified but can be separated again into the original specimens. The identifiers of the original specimens may be tracked. |  |
`http://terminology.hl7.org/v2plusvocab/CodeSystem/specimenRole` | H | Historical Specimen | This identifies a parent specimen to the specimen that is submitted for testing |  |
`http://terminology.hl7.org/v2plusvocab/CodeSystem/specimenRole` | L | Pool | Used when aliquots of liquid individual specimens are combined to form a single specimen representing all of the components that are not individually identified. The identifiers of the original specimens may be tracked. |  |
`http://terminology.hl7.org/v2plusvocab/CodeSystem/specimenRole` | O | Operator Proficiency | Specimen used for testing Operator Proficiency. |  |
`http://terminology.hl7.org/v2plusvocab/CodeSystem/specimenRole` | P | Patient | Used for any patient sample. |  |
`http://terminology.hl7.org/v2plusvocab/CodeSystem/specimenRole` | Q | Control specimen | Used when specimen is the control specimen (either positive or negative). |  |
`http://terminology.hl7.org/v2plusvocab/CodeSystem/specimenRole` | R | Replicate | Used when a patient sample is re-run as a control for a repeat test. |  |
`http://terminology.hl7.org/v2plusvocab/CodeSystem/specimenRole` | V | Verifying Calibrator | Used for periodic calibration checks. |  |

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
