    .descriptionThe US Core Laboratory Result Observation Profile is based upon the US Core Observation Clinical Result Profile and, along with the US Core DiagnosticReport Profile for Laboratory Results Reporting, meets the U.S. Core Data for Interoperability (USCDI) Laboratory requirements. Laboratory results are grouped and summarized using the DiagnosticReport resource, which references Observation resources. Each Observation resource represents an individual laboratory test and result value, a “nested” panel (such as a microbial susceptibility panel) that references other observations, or rarely a laboratory test with component result values. The US Core Laboratory Result Observation Profile sets minimum expectations for the Observation resource to record, search, and fetch laboratory test results associated with a patient to promote interoperability and adoption through common implementation. It identifies which core elements, extensions, vocabularies, and value sets SHALL be present in the resource when using this profile. It provides the floor for standards development for specific use cases.Profile for observations that represent question and answer pairs from Social Determinants of Health (SDOH) screening instruments that are represented in LOINC. The Cross-Group Projects work group granted a variance to US Core on 12/03/2020 - Jira ticket FHIR-29795.

One way is to simply include them in the value set and represent the exceptions in the value. For example, measurement values for a serology test could be "detected", "not detected", "inconclusive", or "specimen unsatisfactory". The alternate way is to use the value element for actual observations and use the explicit dataAbsentReason element to record exceptional values. For example, the dataAbsentReason code "error" could be used when the measurement was not completed. Note that an observation may only be reported if there are values to report. For example differential cell counts values may be reported only when > 0. Because of these options, use-case agreements are required to interpret general observations for null or exceptional values.' vs '"Null" or exceptional values can be represented two ways in FHIR Observations. One way is to simply include them in the value set and represent the exceptions in the value. The alternate way is to use the value element for actual observations and use the explicit dataAbsentReason element to record exceptional values. For a given LOINC question, if the LOINC answer list includes concepts such as 'unknown' or 'not available', they should be used for Observation.value. Where these concepts are not part of the value set for Observation.value, the Observation.dataAbsentReason can be used if necessary and appropriate.'
