Basic↦Biobanking↦Definition↦Specimen / Sample
What is it? Why is it important?
A specimen is a specific quantity of Biological Material /BM) (e.g. blood, tissue, urine, saliva, DNA/RNA, hair, stool) taken from a single subject at a specific time (human, animal, plant or other).
A sample is a single unit, taken from a given specimen.
Specimens can be:
- Alive or deceased
- Of human, animal, plant or other origin
- Infectious (e.g. bacteria, virus)
- Radioactive
- Genetic, non-genetic or genetically modified
Specimens are used:
- For diagnostic, therapeutic, or surgical purposes
- For the development of new treatments or technologies
More
Human specimens should always be treated as biohazardous and potentially infectious.
The following specimens are not considered of human biological origin:
- Commercial reagents containing human components or cells
- Non-human specimens (e.g. laboratory animal or plant specimens)
- Microbiological, viral or fungal agents
Specimens may also be referred to as biospecimens or primary samples.
Samples may also be referred to as biological samples, biosamples, or derivatives.
What do I need to do?
When using specimens for research, familiarise yourself with the following requirements:
- Donors must agree to their BM being used for research purposes:
- In human research the participant or legal representative signs an ICF
- In animal research the owner signs an ICF
- Documentation must be stored in a project database that is compliant with:
- Handling and storage procedures must guarantee ongoing quality and traceability of specimens
The recording of specimens and samples needs to include information on:
- Origin (e.g. person/animal/plant identifiers, health history, diagnosis)
- Handling (e.g. sample workflow)
- Analytical results (e.g. sample analysis, reference range)

To obtain meaningful research results, a large number of samples is often necessary. Having access to sufficient patients with the required characteristics (e.g. lifestyle, age, sex, pathology, genetics) can be challenging.
BBMRI-ERIC is a European biobanking research infrastructure dedicated to support researchers in high quality biomedical research. They manage a catalogue of available biospecimens including its associated data across Europe. As an infrastructure, they can provide you with valuable support in accessing specific biospecimens.
