TypeCodeableConcept
Summarytrue
Comments

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.

Cardinality0..1
Terminology BindingSNOMED CT Body Structures (Example)
TypeCodeableConcept
Comments

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 bodySite.

Specimen.collection.fastingStatus[x]
Element IdSpecimen.collection.fastingStatus[x]
Definition

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

Summarytrue
Comments

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 asObservation.component code` = LOINC 49541-6 (Fasting status - Reported).
