Question 19

A biobank, accredited under ISO 20387:2018, conducts an internal audit and discovers a minor procedural lapse in sample labeling during a specific processing step. This lapse, while a deviation from the established Standard Operating Procedure (SOP), did not compromise the integrity, viability, or traceability of the affected biological samples, as confirmed by subsequent checks. What is the most appropriate course of action for the biobank\'s quality manager to address this finding?

Accepted Answer

Document the deviation, conduct a brief review of the SOP for clarity, provide targeted retraining to the involved personnel, and monitor future labeling practices.

Question 20

A biobank operating under ISO 20387:2018 receives a collection of human tissue samples from a clinical partner. During the initial accessioning process, a critical error occurs where a batch of samples is inadvertently assigned a temporary identification number that is later found to be duplicated across two distinct donor cohorts. This duplication was only discovered during a routine internal audit of the sample inventory system. Considering the foundational requirements of ISO 20387:2018 for maintaining the integrity and traceability of biological material, what is the most appropriate immediate course of action for the biobank to rectify this situation and ensure compliance?

Question 21

A biobank operating under ISO 20387:2018 is audited. The audit team identifies that while individual sample storage conditions are monitored, there is no overarching documented procedure that explicitly details the complete lifecycle of biological material from its initial acquisition through to its eventual disposition, including all intermediate handling, processing, and transfer events. Which fundamental requirement of the standard is most likely not being met?

Accepted Answer

The establishment and maintenance of a documented system for the management of the collection.

Question 22

Consider a biobank that has recently received a significant collection of human tissue samples for a long-term research project. The biobank\'s quality management system is designed to adhere to ISO 20387:2018. During the initial processing and accessioning of these samples, a critical deviation occurred where a subset of samples was inadvertently stored at a temperature outside the validated range for a brief period before being corrected. Which of the following actions is most crucial for the biobank to undertake to maintain compliance with the standard and ensure the integrity of the affected samples and associated data?

Accepted Answer

Immediately document the deviation, assess the potential impact on sample viability and data integrity, and implement corrective and preventive actions (CAPA) to prevent recurrence, while clearly labeling the affected samples with their storage history.

Question 23

During the process of accessioning a new collection of seeds from a remote expedition, a critical piece of information regarding the precise geographical coordinates of the collection site was inadvertently omitted from the initial data entry. The team discovers this oversight during an internal audit before any distribution or further processing of the seeds. What is the most appropriate course of action for the biobank to ensure compliance with the standard\'s requirements for traceability and integrity of biological material?

Accepted Answer

Immediately amend the existing record with the correct geographical coordinates, clearly noting the date and reason for the amendment, and re-verify the associated sample integrity.

Question 24

Consider a scenario where a biobank, accredited under ISO 20387:2018, is preparing to transfer a critical batch of human genomic DNA samples to an external research institution for a multi-site clinical trial. The transfer involves multiple logistical steps, including internal transport from storage to a processing lab, aliquoting, and then external shipping via a specialized courier. What fundamental aspect of biobanking management, as stipulated by the standard, must be rigorously maintained and documented throughout this entire process to ensure sample integrity and regulatory compliance?

Accepted Answer

Comprehensive and unbroken chain of custody documentation

Question 25

When a biobank receives a significant collection of cryopreserved human plasma samples from another accredited biobanking facility for long-term storage and potential future research, what is the paramount consideration for the receiving biobank to ensure compliance with ISO 20387:2018, particularly regarding the integrity and fitness for purpose of the transferred materials?

Accepted Answer

The receiving biobank's documented quality management system must demonstrate its capability to maintain the cryopreservation conditions and traceability of the incoming plasma samples, ensuring their continued suitability for research purposes.

Question 26

Consider a biobank that has recently undergone an external audit. The audit report highlights a recurring issue where the precise sequence of thawing and aliquoting for a specific batch of cryopreserved human plasma samples, intended for a multi-center genomic study, could not be fully reconstructed from the available records. While the samples were ultimately distributed and used, the audit noted a gap in the detailed temporal and procedural logging of these critical post-cryopreservation steps. Which fundamental requirement of ISO 20387:2018 is most directly impacted by this record-keeping deficiency?

Accepted Answer

Ensuring the traceability and integrity of biological material throughout its lifecycle.

Question 28

Consider a biobank specializing in the cryopreservation of human tissue samples for advanced proteomic research. A recent internal audit identified a recurring issue where the temperature logs for a specific ultra-low temperature freezer showed intermittent, brief excursions above the $-70^{\circ}C$ threshold, reaching $-65^{\circ}C$ for periods not exceeding 15 minutes over a 24-hour cycle. The biobank\'s standard operating procedure (SOP) for cryopreservation mandates a stable $-80^{\circ}C$ environment, with excursions above $-70^{\circ}C$ requiring immediate investigation and potential sample quarantine. Given the potential impact on protein structure and stability, which aspect of the biobank\'s quality management system, as guided by ISO 20387:2018, is most critically compromised by these temperature fluctuations?

Accepted Answer

The effectiveness of the corrective and preventive actions (CAPA) process in addressing deviations from established temperature parameters.

Question 29

When establishing a biobanking facility compliant with ISO 20387:2018, what is the most critical documentation requirement to ensure the ethical and legal integrity of biological material throughout its lifecycle, particularly concerning donor rights and research limitations?

Accepted Answer

Comprehensive records detailing sample origin, collection, processing, storage, and any associated donor consent and usage restrictions.

Question 30

A biobank specializing in human plasma for genomic research receives a large shipment of samples. During routine inventory checks, it is discovered that a specific lot, comprising 500 units, experienced an unrecorded temperature excursion during transit, exceeding the acceptable range for a period of 12 hours. The biobank\'s quality management system requires a documented procedure for handling such events. What is the most immediate and critical action to be taken regarding this lot of plasma samples to ensure compliance with biobanking standards and maintain sample integrity?

Accepted Answer

Segregate the affected lot from the general inventory and clearly label it as nonconforming, pending further investigation and disposition.
