    CodeDisplayDefinition
    POSPositiveA presence finding of the specified component / analyte, organism or clinical sign based on the established threshold of the performed test or procedure.
    NEGNegativeAn absence finding of the specified component / analyte, organism or clinical sign based on the established threshold of the performed test or procedure.

    \[Note: Negative does not necessarily imply the complete absence of the specified item.\]
    RResistantBacterial strain inhibited in vitro by a concentration of an antimicrobial agent that is associated with a high likelihood of therapeutic failure.

    \[Note 1: Bacterial strains are categorized as resistant by applying the appropriate breakpoints in a defined phenotypic test system.\]

    \[Note 2: This breakpoint can be altered due to changes in circumstances (e.g., changes in commonly used drug dosages, emergence of new resistance mechanisms).\]
    SSusceptibleBacterial strain inhibited by in vitro concentration of an antimicrobial agent that is associated with a high likelihood of therapeutic success.

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
