  • Include these codes as defined in http://terminology.hl7.org/CodeSystem/v3-ObservationInterpretation
    CodeDisplayDefinition
    HHighThe result for a quantitative observation is above the upper limit of the reference range (as defined for the respective test procedure).

    Synonym: Above high normal
    LLowThe result for a quantitative observation is below the lower limit of the reference range (as defined for the respective test procedure).

    Synonym: Below low normal
    IIntermediateBacterial strain inhibited in vitro by a concentration of an antimicrobial agent that is associated with uncertain therapeutic effect.

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

    \[Note 2: This class of susceptibility implies that an infection due to the isolate can be appropriately treated in body sites where the drugs are physiologically concentrated or when a high dosage of drug can be used.\]

    \[Note 3: This class also indicates a "buffer zone," to prevent small, uncontrolled, technical factors from causing major discrepancies in interpretations.\]

    \[Note 4: These breakpoints can be altered due to changes in circumstances (e.g., changes in commonly used drug dosages, emergence of new resistance mechanisms).\]

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
