## Union of http://hl7.eu/fhir/laboratory/StructureDefinition/Ratio-eu-lab and http://hl7.eu/fhir/laboratory/StructureDefinition/Ratio-eu-lab

This is the set of resources that conform to either of the profiles Ratio (Eu Lab) (http://hl7.eu/fhir/laboratory/StructureDefinition/Ratio-eu-lab) and Ratio (Eu Lab) (http://hl7.eu/fhir/laboratory/StructureDefinition/Ratio-eu-lab). E.g. what you have to deal with if you get resources conforming to one of them

### Structure

Name | Flags | Card. | Type | Description & Constraints
--- | --- | --- | --- | ---
Ratio | C | 0..* |  | A measured ratio using UCUM ele-1: All FHIR elements must have a @value or children rat-1: Numerator and denominator SHALL both be present, or both are absent. If both are absent, there SHALL be some extension present
extension |  | 0..* | Extension | Additional content defined by implementations ele-1: All FHIR elements must have a @value or children ext-1: Must have either extensions or value[x], not both
numerator | S C | 0..1 | ?? | A measured amount using UCUM ele-1: All FHIR elements must have a @value or children qty-3: If a code for the unit is present, the system SHALL also be present
denominator | S C | 0..1 | ?? | A measured amount using UCUM ele-1: All FHIR elements must have a @value or children qty-3: If a code for the unit is present, the system SHALL also be present
