The biobank of Kunshan First People's Hospital, as an important regional biological specimen preservation institution, undertakes the collection, preservation and management of a large number of clinical specimens. BRD BradyLAB Lab series cryogenic labels have been successfully applied in this biobank, providing reliable assurance for specimen identification.
I. Hospital Biobank Management Challenges
Hospital biobanks need to manage specimens from different departments, different disease types and different time points, with large specimen volumes, many types and high traceability requirements. As the carrier of specimen information, labels must have good low-temperature resistance, information readability and traceability compatibility.
II. BRD BradyLAB Solution
In response to hospital biobank needs, BRD BradyLAB provided Lab series cryogenic labels and matching printing consumables. The labels are compatible with commonly used hospital containers such as microcentrifuge tubes and cryovials, with a temperature range covering -196 °C to room temperature, and can interface with hospital LIMS and specimen management systems.
III. Application Results
After the labels were put into use, specimen identification accuracy improved significantly, and specimen retrieval and inventory efficiency increased markedly. In -80 °C freezers and LN₂ environments, the labels adhered firmly with clear information, meeting the hospital biobank's requirements for long-term preservation and standardized management.
IV. Case Value
The successful application of this project verified the applicability and reliability of BRD BradyLAB Lab series cryogenic labels in hospital biobank scenarios, providing referenceable specimen identification experience for similar medical institutions.
V. Future Outlook
BRD BradyLAB will continue to cooperate with medical institutions at all levels, continuously optimizing products and services to help improve the level of biobank management in China.
Related Compliance Standards
Label applications in hospital biobanks must meet the specimen identification traceability requirements of ISO 20387:2018 "Biobanking — General requirements for biobanking"; medical laboratory quality management refers to ISO 15189:2022; and label barcode quality refers to ISO/IEC 15416.

FAQ
Q: What special requirements apply to labels for hospital biobanks?
Both low-temperature cryopreservation of clinical specimens and information traceability must be considered. Labels must withstand -80 °C/-196 °C environments and interface with hospital LIS/HIS systems to ensure strict correspondence between specimens and patient information.
Q: What are typical uses of cryogenic labels in hospital biobanks?
Cryogenic barcode labels are used for vial-level identification of cryovials, while box-level identification of cryoboxes can incorporate RFID; specimen check-in and check-out are tracked throughout via barcode scanning.
Q: What risks arise if labels fall off in a hospital biobank?
Loss of specimen identity will render specimens invalid or even lead to incorrect clinical decisions—a major quality risk. Therefore, product selection and labeling must be strictly validated.
Standard Requirements for Hospital Biobank Identification
Specimens preserved in hospital biobanks carry both clinical and research value, and identification standards directly affect specimen usability and compliance. Specimen identification management in biobanks can refer to the requirements of ISO 20387:2018 for biobanks, the core of which is to ensure that every specimen has a unique identity, complete information and traceability throughout collection, processing, storage and distribution.
| Stage | Identification Key Points |
|---|---|
| Collection | Verify patient/specimen number on site; scan back immediately after labeling |
| Processing | Aliquots retain the parent specimen number with an added suffix to avoid misalignment |
| Storage | Labels withstand -80 °C / -196 °C; spot-check rescanning after cryopreservation |
| Distribution | Scan and record on check-out; log destination and purpose |
Label Performance in LN₂ and Ultra-Low Temperature Environments
Hospital biobanks commonly use -80 °C ultra-low temperature (ULT) freezers and -196 °C LN₂ dewars for specimen storage. Labels must not become brittle or detach at the target temperature, must remain barcode-readable, and must withstand repeated freeze–thaw cycles. Lab series labels use low-temperature-resistant face stock and low-Tg adhesives; after 50 repeated freeze–thaw cycles in LN₂, they maintain over 99% adhesion stability, with barcode contrast ratio ≥ 85%, enabling direct scanning in the frozen state.
Overall Benefits of Biobank Identification
Standardized label management greatly improves biobank inventory efficiency—traditional tube-by-tube scanning takes hours, whereas with labels and a scanning system, whole-box verification can be completed within minutes. For hospitals, this means a lower specimen error rate, higher credibility of research data, and smoother ethics and compliance audits.
Full-Process Traceability Design for Hospital Biobank Labels
Specimen workflows in hospital biobanks involve long chains and many participating departments; label traceability design must cover the entire lifecycle of collection, aliquoting, cryopreservation, check-out, experimentation and disposal. It is recommended to use "unique number + scan verification + system record" as the main line, with scan records at every node, ensuring that any specimen can be traced to its source, processing history and destination.
Designing Specimen Numbering Rules
Reasonable specimen numbering rules are the foundation of traceability. A structure of "biobank code + storage date + serial number + specimen type + aliquot suffix" is recommended, ensuring both uniqueness and ease of manual recognition and system retrieval. Once established, the numbering rules should be written into the SOP and remain stable long-term, avoiding mid-course changes that make historical specimens unmatchable.
Label Validation in LN₂ and Ultra-Low Temperature Environments
| Validation Item | LN₂ -196 °C | ULT -80 °C |
|---|---|---|
| Face stock | Polyimide (PI), flexible and non-brittle | Polyester (PET) or PI |
| Freeze–thaw cycles | ≥50 cycles without failure | ≥30 cycles without failure |
| Barcode readability | Contrast ratio ≥85% after cryopreservation | Contrast ratio ≥80% after cryopreservation |
| Adhesion stability | Over 99% | Over 99% |
Benefit Assessment of Biobank Label Management
Standardized label management brings multiple benefits to hospital biobanks: reduced specimen error rate, improved inventory efficiency (whole-box batch scanning replaces tube-by-tube verification), higher credibility of research data, and smoother ethics review and compliance audits. For hospitals handling large volumes of clinical research specimens, this is a foundational undertaking with small investment and significant returns.
Ethics and Compliance in Hospital Biobanks
Hospital biobanks are subject to both ethics review and regulatory constraints; specimen traceability is both an ethical requirement (informed consent and specimen destination) and a compliance requirement (ISO 20387). Standardized label management provides the foundation for full-lifecycle specimen traceability and is a necessary condition for the robust operation of biobanks.
