Czech national profile defines how to represent Specimens in HL7 FHIR for the purpose of this guide. 

 
Specimens are samples of material that may be: 
• taken from a biological entity, living or dead 
• taken from a physical object or environment 
Some samples are biological and may contain one or more components including, but not limited to, cellular molecules, cells, tissues, organs, body fluids, embryos, and body excretions. The source of samples includes substances used for diagnostic and environmental testing. The focus of sample sources is on the process of collecting, maintaining, and processing the sample, as well as where the sample came from. 

**Usages:**

* Refer to this Profile: [Specimen (CZ Core)](StructureDefinition-cz-specimen.md)
* Examples for this Profile: [Specimen/Specimen-example-animal](Specimen-Specimen-example-animal.md) and [Specimen/Specimen-example-environment](Specimen-Specimen-example-environment.md)
