Code | Display | Definition |
true | true | Boolean true. |
false | false | Boolean false. |
trace | Trace Amount Detected | The content is greater than zero, but too small to be quantified. |
sufficient | Sufficient Quantity | The specific quantity is not known, but is known to be non-zero and is not specified because it makes up the bulk of the material. |
withdrawn | Value Withdrawn | The value is no longer available. |
nil-known | Nil Known | The are no known applicable values in this context. |

Explanation of the columns that may appear on this page:
Lvl | A few code lists that FHIR defines are hierarchical - each code is assigned a level. For value sets, levels are mostly used to organize codes for user convenience, but may follow code system hierarchy - see Code System for further information |
Source | 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). If the code is in italics, this indicates that the code is not selectable ('Abstract') |
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 |
