It is possible that isolates with MICs above the susceptible breakpoint that lack resistance mechanisms may be encountered within the wild-type distribution subsequent to the time the susceptible-only breakpoint is set. <br/> NOTE 2: For strains yielding results in the "nonsusceptible" category, organism identification and antimicrobial susceptibility test results should be confirmed.<br/> Synonym: decreased susceptibility.</td></tr><tr><td><a href="http://hl7.org/fhir/R4/v3/ObservationInterpretation/cs.html#v3-ObservationInterpretation-S-DD">S-DD</a></td><td>Susceptible-dose dependant</td><td/></tr></table></li></ul></div> </text> <url value="http://hl7.org/fhir/us/hai/ValueSet/2.16.840.1.113883.13.13"/> <name value="NHSNDrugSusceptibilityFindingCode"/> <status value="active"/> <date value="2019-10-11T15:43:03-04:00"/> <description value="Codes representing a drug susceptibility finding."/> <compose> <include> <system value="http://terminology.hl7.org/CodeSystem/v3-ObservationInterpretation"/> <concept> <code value="I"/> <display value="Intermediate"/> </concept> <concept> <code value="R"/> <display value="Resistant"/> </concept> <concept> <code value="S"/> <display value="Susceptible"/> </concept> <concept> <code value="NS"/> <display value="Non-Susceptible"/> </concept> <concept> <code value="S-DD"/> <display value="Susceptible-dose dependant"/> </concept> </include> </compose> </ValueSet>
