Class TSubstanceAmount
Unit
bsFhir_r4
Declaration
type TSubstanceAmount = class(TBackboneElement)
Description
Chemical substances are a single substance type whose primary defining element is the molecular structure. Chemical substances shall be defined on the basis of their complete covalent molecular structure; the presence of a salt (counter-ion) and/or solvates (water, alcohols) is also captured. Purity, grade, physical form or particle size are not taken into account in the definition of a chemical substance or in the assignment of a Substance ID. If the element is present, it must have a value for at least one of the defined elements, an @id referenced from the Narrative, or extensions

Properties
|
property amount : TElement read Getamount write Setamount; |
|
Used to capture quantitative values for a variety of elements. If only limits are given, the arithmetic mean would be the average. If only a single definite value for a given element is given, it would be captured in this field.
|
|
property amountType : TCodeableConcept read GetamountType write SetamountType; |
|
Most elements that require a quantitative value will also have a field called amount type. Amount type should always be specified because the actual value of the amount is often dependent on it. EXAMPLE: In capturing the actual relative amounts of substances or molecular fragments it is essential to indicate whether the amount refers to a mole ratio or weight ratio. For any given element an effort should be made to use same the amount type for all related definitional elements.

|
property amountText : string read GetamountText write SetamountText; |
|
A textual comment on a numeric value.
|
|
property amountTextElement : Tstring read GetamountTextElement write SetamountTextElement; |
|
|
|
property referenceRange : TSubstanceAmountReferenceRange read GetreferenceRange write SetreferenceRange; |
|
Reference range of possible or expected values.
