A sample to be used for analysis.

Identifiers used for specimen identification. These could include but are not limited to identifiers generated upon collection, accessioning, or other reasons for labeling a specimen.

These are business identifiers, not Specimen.id - the resource identifier. More information in this (see discussion ). For accession identifiers, the Accession Identifier code, ACSN, should be used in the Identifier.type.

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 substance, a biologically-derived product, or a device.

Must know the subject context.

Time when specimen was is received by the testing laboratory 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 specimen is derived by some processing step (e.g. an aliquot or isolate or extracted nucleic acids from clinical samples) or one of many specimens 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.

This element signifies if the specimen is part of a group or pooled.

The role or reason for the specimen in the testing workflow.

A physical feature or landmark on a specimen, highlighted for context by the collector of the specimen (e.g. surgeon), that identifies the type of feature as well as its meaning (e.g. the red ink indicating the resection margin of the right lobe of the excised prostate tissue or wire loop at radiologically suspected tumor location).

The landmark or feature being highlighted.

Description of the feature of the specimen.

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.

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

The procedure event during which the specimen was collected (e.g. the surgery leading to the collection of a pathology sample).

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 Reasons for using BodyStructure reference include: 1.) Need to be handled as identify a separate resource instead of an inline coded element specific site instance (e.g. to identify and track separately) then use a specific mole), 2.) a single pre-coordinated coded concept for the standard extension body site does not exist, 3.) a desire to represent bodySite . using multiple attributes (e.g. modifiers).

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 'pre-coordinated 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 method used to process the specimen.

Material used in The performer of the processing step. of the specimen.

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

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 Material used in some circumstances. the processing step.

Textual description A record of the container. 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 type of container associated with holding the specimen (e.g. slide, aliquot, etc.). specimen. The recursive nature of containers; i.e. blood in tube in tray in rack is not addressed here.

The capacity (volume or other measure) device resource for the the container may contain. holding the specimen. If the container is in a holder then the referenced device will point to a parent device.

Introduced substance to preserve, maintain The quantity of specimen in the container; may be volume, dimensions, or enhance other appropriate measurements, depending on the specimen. Examples: Formalin, Citrate, EDTA. specimen type.

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

The specimen condition can be used to assess its quality or 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 its quality or 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).
