| Code | Display |
| < | Below absolute low-off instrument scale |
| > | Above absolute high-off instrument scale |
| A | Abnormal (applies to non-numeric results) |

| AC | Anti-complementary substances present |
| B | Better-use when direction not relevant |
| D | Significant change down |
| DET | Detected |
| H | Above high normal |
| HH | Above upper panic limits |
| I | Intermediate. Indicates for microbiology susceptibilities only. |
| IND | Indeterminate |
| L | Below low normal |
| LL | Below lower panic limits |
| MS | Moderately susceptible. Indicates for microbiology susceptibilities only. |
| N | Normal (applies to non-numeric results) |
| ND | Not Detected |

| TOX | Cytotoxic substance present |
| U | Significant change up |
| VS | Very susceptible. Indicates for microbiology susceptibilities only. |
| W | Worse-use when direction not relevant |
| WR | Weakly reactive |
| null | No range defined, or normal ranges don't apply |

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 |
| 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) |
| 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 |
