Laboratory result qualifier values expressing presence, absence, and related ordinal findings (e.g. detected/not detected, positive/negative, reactive/non-reactive, ordinal "+" gradings). This value set is aligned with the eHDSI PresenceAbsence value set adopted by the eEHMSEG (https://fhir.ehdsi.eu/laboratory/ValueSet-eHDSIPresenceAbsence.html).

 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](http://hl7.org/fhir/R4/datatypes.html#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 |
