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. The kind of material that forms the specimen. 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. 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. Details concerning a service request that required a specimen to be collected. Details concerning the specimen collection. Details concerning processing and processing steps for the specimen.

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