Short | Genomic Structural Variant Copy Number |
Comments | Copy number variants are often described with a single copy number value. However, due to the nature of assays, such as qPCR and microarray, it can be difficult to assign an exact copy number. Therefore, labs sometimes report a range instead of an exact copy number. They may alternatively choose to report decimal numbers, even if whole numbers are biologically correct. In general, it can be difficult to estimate a copy number from measurements taken on a heterogenous population of cells, such as a tumor. As indicated in the ISCN 2020 specifications, it is appropriate to express the measurements using a range. Furthermore, regardless of cell population, many assays use fluorescent probes to detect copy number. These testing methodologies do not always provide an exact, discrete value for this data point. |

Definition | The genomic alternate allele is the contiguous segment of DNA in the test sample that differs from the reference allele at the same location and thus defines a variant.

Examples include systolic and diastolic component observations for blood pressure measurement and multiple component observations for genetics observations. |

Some observations have multiple component observations. These component observations are expressed as separate code value pairs that share the same attributes. Examples include systolic and diastolic component observations for blood pressure measurement and multiple component observations for genetics observations. |
Short | Genomic Structural Variant Copy NumberComponent results |
Comments | Copy number variants are often described with a single copy number value. However, due to the nature of assays, such as qPCR and microarray, it can be difficult to assign an exact copy number. Therefore, labs sometimes report a range instead of an exact copy number. They may alternatively choose to report decimal numbers, even if whole numbers are biologically correct. In general, it can be difficult to estimate a copy number from measurements taken on a heterogenous population of cells, such as a tumor. As indicated in the ISCN 2020 specifications, it is appropriate to express the measurements using a range. Furthermore, regardless of cell population, many assays use fluorescent probes to detect copy number. These testing methodologies do not always provide an exact, discrete value for this data point.

Definition | The actual focus of an observation when it is not the patient of record representing something or someone associated with the patient such as a spouse, parent, fetus, or donor. For example, fetus observations in a mother's record. The focus of an observation could also be an existing condition, an intervention, the subject's diet, another observation of the subject, or a body structure such as tumor or implanted device. An example use case would be using the Observation resource to capture whether the mother is trained to change her child's tracheostomy tube. In this example, the child is the patient of record and the mother is the focus. | ||||

70. Observation.dataAbsentReason | |||||
Definition | Provides a reason why the expected value in the element Observation.value[x] is missing. | ||||
Short | Why the result is missing | ||||
Comments | 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. 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. | ||||

Comments | May include general statements about the observation, or statements about significant, unexpected or unreliable results values, or information about its source when relevant to its interpretation. The CodedAnnotation data type, while not allowing for or intending to make the content computable, does allow the author to indicate the type of note. This does not replace the use of interpretation, value, or component values. One important note is that Annotation is a FHIR data type, this is NOT about annotations in the genomic context. | ||||

An observation may have both a value (e.g. an Apgar score) and component observations (the observations from which the Apgar score was derived). If a value is present, the datatype for this element should be determined by Observation.code.

Definition | Provides a reason why the expected value in the element Observation.component.value[x] is missing. | ||||
Short | Why the component result is missing | ||||
Comments | "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. For example, measurement values for a serology test could be "detected", "not detected", "inconclusive", or "test not done". 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. Because of these options, use-case agreements are required to interpret general observations for exceptional values. | ||||

Short | Provides guide for interpretation of component result | ||||
Comments | Most observations only have one generic reference range. Systems MAY choose to restrict to only supplying the relevant reference range based on knowledge about the patient (e.g., specific to the patient's age, gender, weight and other factors), but this might not be possible or appropriate. Whenever more than one reference range is supplied, the differences between them SHOULD be provided in the reference range and/or age properties. | ||||
