Concepts

This case-sensitive code system http://terminology.hl7.org/CodeSystem/v2-0937 defines the following codes in a Is-A hierarchy:

CodeDisplayDefinitionV2 Concept CommentV2 Concept Comment As Published
AOE Ask at Order Entry Ask at Order Entry Sub-type of QST (Question) - OBX-5 value is answer to an Ask at Order Entry question Sub-type of QST (Question) - OBX-5 value is answer to an Ask at Order Entry question
ASC Ask at Specimen Collection Ask at Specimen Collection Sub-type of QST (Question) - OBX-5 value is answer to an Ask at Specimen Collection question Sub-type of QST (Question) - OBX-5 value is answer to an Ask at Specimen Collection question
MCS Micro Culture Status Sub-type of RSLT (Result) This term identifies observations that give overall culture outcome, when no specific organism is being named. Examples are: no growth, normal flora
MID Micro Isolate Descriptor Sub-type of RSLT (Result) This term identifies any other observations about the isolate. Examples: catalase positive, hemolytic, etc.
MIG Micro Isolate Growth Quantity Sub-type of RSLT (Result) This term identifies growth levels of an isolate – can be numeric or categorical. Examples: <10,000 CFU, >100,00 CFU, Few, Moderate, Many, etc.
MIN Micro Isolate Name Sub-type of RSLT (Result) This term identifies observations that name a specific organism either at the species or the genus level. Examples are: Genus Serratia, Neisseria meningitidis, Escherichia coli O157:H7, but also identification on a culture plate like presumptive Proteus species.
MIR Micro Isolate Related Micro Isolate Related Sub-type of RSLT (Result) - qualifies the result as an isolate. Sub-type of RSLT (Result) - qualifies the result as an isolate.
MIRM Micro Isolate Related Modifier Micro Isolate Related Modifier Sub-type of RSLT (Result) - result is a modifier of the isolate (e.g., Few, Some, etc.) Sub-type of RSLT (Result) - result is a modifier of the isolate (e.g., Few, Some, etc.)
MNIR Micro Non-Isolate Related Micro Non-Isolate Related Sub-type of RSLT (Result) - qualifies result as microbiology not related to any isolate (e.g., gram stain observations) Sub-type of RSLT (Result) - qualifies result as microbiology not related to any isolate (e.g., gram stain observations)
MOD Micro Other Descriptor Sub-type of RSLT (Result) This term identifies observations that do not fit the culture status, but is not at the isolate level.
MSS Micro Sample Stain Sub-type of RSLT (Result) This term identifies observations on gram stains (and other stains or smears) on the clinical sample. Examples are: many gram positive rods, acid fast bacteria seen, etc.
SUP Supplemental Result Supplemental Result Sub-type of RSLT (Result) - result coming over is additional material, for example points on a graph, an image, raw instrument data, links to related observations, etc. Sub-type of RSLT (Result) - result coming over is additional material, for example points on a graph, an image, raw instrument data, links to related observations, etc.
SUR Susceptibility Related Susceptibility Related Sub-type of RSLT (Result) - result value is for micro susceptibility/sensitivity Sub-type of RSLT (Result) - result value is for micro susceptibility/sensitivity
UNSP Unspecified Unspecified Sub-type of RSLT (Result) - result falls outside of the other sub-types. Sub-type of RSLT (Result) - result falls outside of the other sub-types.
