Dieses Profil bildet eine Laboruntersuchung ab.

Laboruntersuchungen können als Messung oder als Berechnung erfolgen.

Eine Laboruntersuchung als Messung beschreibt die quantitative oder qualitative Untersuchung eines spezifischen Laborparameters in einem definierten Probenmaterial; z. B. die Untersuchung des Hämoglobin-(Hb-)Werts als Konzentration im Blut. Der Bezug zur Probe, anhand derer die Messung vorgenommen wurde, muss erkennbar sein.

Berechnete Laborergebnisse können auf Messungen basieren, z.B. kann die berechnete GFR (glomeruläre Filtrationsrate) auf einem gemessenen Kreatinin-Wert im Serum basieren.

Represents either a lab simple observation or the group of observations produced by a laboratory study.

The metadata about the resource. This is content that is maintained by the infrastructure. Changes to the content might not always be associated with version changes to the resource.

The version specific identifier, as it appears in the version portion of the URL. This value changes when the resource is created, updated, or deleted.

The server assigns this value, and ignores what the client specifies, except in the case that the server is imposing version integrity on updates/deletes.

When the resource last changed - e.g. when the version changed.

This value is always populated except when the resource is first being created. The server / resource manager sets this value; what a client provides is irrelevant. This is equivalent to the HTTP Last-Modified and SHOULD have the same value on a read interaction.

A reference to a set of rules that were followed when the resource was constructed, and which must be understood when processing the content. Often, this is a reference to an implementation guide that defines the special rules along with other profiles etc.

Asserting this rule set restricts the content to be only understood by a limited set of trading partners. This inherently limits the usefulness of the data in the long term. However, the existing health eco-system is highly fractured, and not yet ready to define, collect, and exchange data in a generally computable sense. Wherever possible, implementers and/or specification writers should avoid using this element. Often, when used, the URL is a reference to an implementation guide that defines these special rules as part of it's narrative along with other profiles, value sets, etc.

R5: Observation.bodyStructure (new:Reference(BodyStructure))

Element Observation.bodyStructure has a context of Observation based on following the parent source element upwards and mapping to Observation. Element Observation.bodyStructure has no mapping targets in FHIR R4. Typically, this is because the element has been added (is a new element). Only used if not implicit in code found in Observation.code or bodySite is used. In many systems, this may be represented as a related observation instead of an inline component.

EHDSObservation.anatomicLocation

R5: Observation.triggeredBy (new:BackboneElement)

Element Observation.triggeredBy has a context of Observation based on following the parent source element upwards and mapping to Observation. Element Observation.triggeredBy has no mapping targets in FHIR R4. Typically, this is because the element has been added (is a new element).

May be used to represent additional information that is not part of the basic definition of the element. To make the use of extensions safe and manageable, there is a strict set of governance applied to the definition and use of extensions. Though any implementer can define an extension, there is a set of requirements that SHALL be met as part of the definition of the extension.

There can be no stigma associated with the use of extensions by any application, project, or standard - regardless of the institution or jurisdiction that uses or defines the extensions. The use of extensions is what allows the FHIR specification to retain a core level of simplicity for everyone.

R5: Observation.triggeredBy.observation (new:Reference(Observation))

Element Observation.triggeredBy.observation is part of an existing definition because parent element Observation.triggeredBy requires a cross-version extension.

Value of extension - must be one of a constrained set of the data types (see Extensibility for a list).

When the result is a Diagram or Picture (Microbiology), then the Attachment data type should be used. In FHIR R4 this can be done by preadopting the R5 Observation.value[x] element using the cross-version extension.

Element Observation.value[x] is mapped to FHIR R4 element Observation.value[x] as SourceIsBroaderThanTarget. The mappings for Observation.value[x] do not cover the following types: Attachment, Reference. The target context Observation.value[x] is a choice-type element and cannot directly hold extensions. The context is moved up to parent element Observation.

• An observation may have:
  1. a single value here
  2. both a value and a set of related or component values
  3. only a set of related or component values.
• If a value is present, the datatype for this element should be determined by the code.
• CodeableConcept with just a text would be used instead of a string if the field was usually coded, or if the type associated with the code defines a coded value.
• Attachment is used if the observation result value is a binary file such as an image. If the observation result value is derived from the binary file (for example 'X' detected and here is the the proof in this image), the binary file may be directly represented using DocumentReference and referenced by derivedFrom.
• The usage of valueReference is restricted to the MolecularSequence resource when used as a definitional resource, not as a patient-specific finding. .
• For additional guidance, see the Notes section below.

Benennung eines Test-Profils als Code.

Codes may be defined very casually in enumerations, or code lists, up to very formal definitions such as SNOMED CT - see the HL7 v3 Core Principles for more information. Ordering of codings is undefined and SHALL NOT be used to infer meaning. Generally, at most only one of the coding values will be labeled as UserSelected = true.

Allows for alternative encodings within a code system, and translations to other code systems.

The identification of the code system that defines the meaning of the symbol in the code.

The URI may be an OID (urn:oid:...) or a UUID (urn:uuid:...). OIDs and UUIDs SHALL be references to the HL7 OID registry. Otherwise, the URI should come from HL7's list of FHIR defined special URIs or it should reference to some definition that establishes the system clearly and unambiguously.

Need to be unambiguous about the source of the definition of the symbol.

The version of the code system which was used when choosing this code. Note that a well-maintained code system does not need the version reported, because the meaning of codes is consistent across versions. However this cannot consistently be assured, and when the meaning is not guaranteed to be consistent, the version SHOULD be exchanged.

Where the terminology does not clearly define what string should be used to identify code system versions, the recommendation is to use the date (expressed in FHIR date format) on which that version was officially published as the version date.

A symbol in syntax defined by the system. The symbol may be a predefined code or an expression in a syntax defined by the coding system (e.g. post-coordination).

Need to refer to a particular code in the system.

A representation of the meaning of the code in the system, following the rules of the system.

Note that FHIR strings SHALL NOT exceed 1MB in size

Need to be able to carry a human-readable meaning of the code for readers that do not know the system.

Benennung des Test-Profils als Freitext.

Very often the text is the same as a displayName of one of the codings.

The codes from the terminologies do not always capture the correct meaning with all the nuances of the human using them, or sometimes there is no appropriate code at all. In these cases, the text is used to capture the full meaning of the source.

Der zlog-Wert ist ein Relativwert, der auf einer logarithmischen Skala angibt, um wie viele Standardabweichungen ein Messwert vom Mittelwert des Referenzkollektivs abweicht. Er kann ergänzend, orientierend zur Bewertung eines Messergebnisses herangezogen werden.

Berechnung zlog-Wert zum Laborergebnis (x):

zlog = (log(x) –(log(UG)+log(OG))/2)*3,92/(log(OG)–log(UG))

(UG),(OG) sind die Unter- und Obergrenzen des Referenzintervalls

Interpretation des zlog-Wertes:

• Sein Referenzintervall liegt methodenunabhängig stets zwischen – 1,96 und + 1,96
• Stark erniedrigte oder erhöhte Laborergebnisse führen zu zlog-Werten um – 5 bzw. + 5.
