A sample to be used for analysis.

Id for specimen.

The identifier assigned by the lab when accessioning specimen(s). This is not necessarily the same as the specimen identifier, depending on local lab procedures.

The availability of the specimen.

This element is labeled as a modifier because the status contains codes that mark the resource as not currently valid.

The kind of material that forms the specimen.

The type can change the way that a specimen is handled and drives what kind of analyses can properly be performed on the specimen. It is frequently used in diagnostic work flow decision making systems.

Where the specimen came from. This may be from patient(s),from a location (e.g., the source of an environmental sample), or a sampling of a substance or a device.

Must know the subject context.

Time when specimen was received for processing or testing.

Reference to the parent (source) specimen which is used when the specimen was either derived from or a component of another specimen.

The parent specimen could be the source from which the current the current specimen is derived by some by some processing step (e.g. an aliquot or isolate or step (e.g. an aliquot or isolate or extracted nucleic acids from clinical samples) or one acids from clinical samples) or one of many specimens that were combined to that were combined to create a pooled sample.

Details concerning a service request that required a specimen to be collected.

The request may be explicit or implied such with a ServiceRequest that requires a blood draw.

Details concerning the specimen collection.

Person who collected the specimen.

Time when specimen was collected from subject - the physiologically relevant time.

The span of time over which the collection of a specimen occurred.

The quantity of specimen collected; for instance the volume of a blood sample, or the physical measurement of an anatomic pathology sample.

A coded value specifying the technique that is used to perform the procedure.

Anatomical location from which the specimen was collected (if subject is a patient). This is the target site. This element is not used for environmental specimens.

If the use case requires BodySite to be handled as a separate resource instead of an inline coded element (e.g. to identify and track separately) then use the standard extension body-structure bodySite .

Abstinence or reduction from some or all food, drink, or both, for a period of time prior to sample collection.

Many diagnostic tests require fasting to facilitate accurate interpretation.

Representing fasting status using this element is preferred to representing it with an observation using a 'precoordinated code' such as LOINC 2005-7 (Calcium [Moles/​time] in 2 hour Urine --12 hours fasting), or using a component observation such as Observation.component code` = LOINC 49541-6 (Fasting status - Reported).

Details concerning processing and processing steps for the specimen.

Textual description of procedure.

A coded value specifying the procedure used to process the specimen.

Material used in the processing step.

A record of the time or period when the specimen processing occurred. For example the time of sample fixation or the period of time the sample was in formalin.

The container holding the specimen. The recursive nature of containers; i.e. blood in tube in tray in rack is not addressed here.

Id for container. There may be multiple; a manufacturer's bar code, lab assigned identifier, etc. The container ID may differ from the specimen id in some circumstances.

Textual description of the container.

The type of container associated with the specimen (e.g. slide, aliquot, etc.).

The capacity (volume or other measure) the container may contain.

The quantity of specimen in the container; may be volume, dimensions, or other appropriate measurements, depending on the specimen type.

Introduced substance to preserve, maintain or enhance the specimen. Examples: Formalin, Citrate, EDTA.

A mode or state of being that describes the nature of the specimen.

The specimen condition can be used to assess it's quality or it's appropriateness for a specific test.

Specimen condition is an observation made about the specimen. It's a point-in-time assessment. It can be used to assess it's quality or it's appropriateness for a specific test.

To communicate any details or issues about the specimen or during the specimen collection. (for example: broken vial, sent with patient, frozen).
