ObservationInterpretation One or more codes specifying a rough qualitative interpretation of the observation, such as "normal", "abnormal", "below normal", "change up", "resistant", "susceptible", etc. Discussion: These interpretation codes are sometimes called "abnormal flags", however, the judgment of normalcy is just one of the common rough interpretations, and is often not relevant. For example, the susceptibility interpretations are not about "normalcy", and for any observation of a pathologic condition, it does not make sense to state the normalcy, since pathologic conditions are never considered "normal."
Lvl | Type, Domain name and/or Mnemonic code | Concept ID | Mnemonic | Print Name | Definition/Description
--- | --- | --- | --- | --- | ---
1 | A: ObservationInterpretationChange | A10214 |  |  | Change of quantity and/or severity. At most one of B or W and one of U or D allowed.
2 | L: (B) | C10215 | B | better | Better (of severity or nominal observations)
2 | L: (D) | C10218 | D | decreased | Significant change down (quantitative observations, does not imply B or W)
2 | L: (U) | C10217 | U | increased | Significant change up (quantitative observations, does not imply B or W)
2 | L: (W) | C10216 | W | worse | Worse (of severity or nominal observations)
1 | A: ObservationInterpretationExceptions | A10225 |  |  | Technical exceptions. At most one allowed. Does not imply normality or severity.
2 | L: (>) | C10227 | > | high off scale | Above absolute high-off instrument scale. This is statement depending on the instrument, logically does not imply LL or L (e.g., if the instrument is inadequate). If an off-scale value is also high or critically high one must also report H and HH respectively.
2 | L: (<) | C10226 | < | low off scale | Below absolute low-off instrument scale. This is statement depending on the instrument, logically does not imply LL or L (e.g., if the instrument is inadequate). If an off-scale value is also low or critically low one must also report L and LL respectively.
1 | A: ObservationInterpretationNormality | A10206 |  |  | Normality, Abnormality, Alert. Concepts in this category are mutually exclusive, i.e., at most one is allowed.
2 | L: (N) | C10207 | N | Normal | Normal (for all service types)
2 | S: ObservationInterpretationNormalityAbnormal (A) | S10208 | A | Abnormal | Abnormal (for nominal observations, all service types)
3 | S: ObservationInterpretationNormalityAlert (AA) | S10211 | AA | Abnormal alert | Abnormal alert (for nominal observations and all service types)
4 | L: (HH) | C10213 | HH | High alert | Above upper alert threshold (for quantitative observations)
4 | L: (LL) | C10212 | LL | Low alert | Below lower alert threshold (for quantitative observations)
3 | S: ObservationInterpretationNormalityHigh (H) | S10210 | H | High | Above high normal (for quantitative observations)
4 | L: (HH) | C10213 | HH | High alert | Above upper alert threshold (for quantitative observations)
3 | S: ObservationInterpretationNormalityLow (L) | S10209 | L | Low | Below low normal (for quantitative observations)
4 | L: (LL) | C10212 | LL | Low alert | Below lower alert threshold (for quantitative observations)
1 | A: ObservationInterpretationProtocolInclusion | A19759 |  |  |
2 | S: ObservationInterpretationOustsideThreshold (EX) | S21634 | EX | outside threshold | Definition:The observation/test result is interpreted as being outside the inclusion range for a particular protocol within which the result is being reported. Example:A positive result on a Hepatitis screening test.
3 | L: (HX) | C21636 | HX | above high threshold | Definition:The numeric observation/test result is interpreted as being above the high threshold value for a particular protocol within which the result is being reported. Example:An ALT (SGOT) result above a protocol-defined threshold value of 2.5 times the upper limit of normal based on the subject's sex and age.
3 | L: (LX) | C21635 | LX | below low threshold | Definition:The numeric observation/test result is interpreted as being below the low threshold value for a particular protocol within which the result is being reported. Example:A Total White Blood Cell Count falling below a protocol-defined threshold value of 3000/mm^3
1 | A: ObservationInterpretationSusceptibility | A10219 |  |  | Microbiology: interpretations of minimal inhibitory concentration (MIC) values. At most one allowed.
2 | L: (I) | C10221 | I | intermediate | Intermediate
2 | L: (MS) | C10222 | MS | moderately susceptible | Moderately susceptible
2 | L: (R) | C10220 | R | resistent | Resistent
2 | L: (S) | C10223 | S | susceptible | Susceptible
2 | L: (VS) | C10224 | VS | very susceptible | Very susceptible
