/// A sample to be used for analysis.
///
/// The Specimen resource describes a physical sample (such as blood, tissue,
/// urine, or an environmental sample) that is collected and used for laboratory
/// or diagnostic analysis. It captures the material type, its source subject,
/// collection details, processing steps, and the containers holding the sample.
/// It is central to laboratory and diagnostic workflows in FHIR R5.
///
/// A Specimen typically originates as the target of a service request (for
/// example an order for a lab test), is collected from a subject such as a
/// patient, may pass through one or more processing steps (centrifugation,
/// fixation, staining, and so on), and is ultimately placed into one or more
/// containers before being analyzed. The resulting observations and diagnostic
/// reports commonly reference the Specimen that was used to produce them,
/// making it a key link between a clinical order and its results.
///
/// # Related resources
///
/// - [`Patient`](crate::r5::resources::patient::Patient) or other subject from
///   which the specimen was obtained.
/// - `ServiceRequest`, which may prompt the collection of a specimen.
/// - `Observation` and `DiagnosticReport`, which commonly reference the
///   specimen used to produce their results.
/// - [`CodeableConcept`](crate::r5::types::CodeableConcept), used throughout
///   this resource to represent coded concepts such as specimen type, role,
///   and condition.
///
/// # Examples
///
/// ```
/// use fhir::r5::resources::specimen::Specimen;
///
/// let value = Specimen::default();
/// let json = ::serde_json::to_value(&value).unwrap();
/// let back: Specimen = ::serde_json::from_value(json).unwrap();
/// assert_eq!(value, back);
