SNOMED CT Specimen

The Specimen hierarchy contains concepts representing entities that are obtained (usually from a patient) for examination or analysis. Specimen concepts can be defined by attributes which specify: the normal or abnormal body structure from which they are obtained; the procedure used to collect the specimen; the source from which it was collected; and the substance of which it was comprised.

Examples of Specimen concepts:

• Specimen from prostate obtained by needle biopsy (specimen)
• Urine specimen obtained by clean catch procedure (specimen)
