Development↦Biobanking↦Quality Control↦Quality Control Indicators
Was betrifft es? Warum ist das wichtig?
Quality Control (QC) is an integral part of a Quality Management System. An aspect of QC in biobanking is the definition and measurement of Quality-Control-Indicators. QC-Indicators are performance indicators regarding critical biobanking steps that must be monitored and controlled.
The performance of QC-indicators:
- Allow for the ongoing monitoring of biobank operational processes
- Indicate whether the compliance of Quality expectations are met
- Feed into the implementation of biobanking improvement measures
QC-Indicators provide information on the compliance with:
- Staff qualification and training
- Sample workflow processes (e.g. process relevant SOPs/WIs)
- Biobank governance,
- Ethics requirements (e.g. EC, Declaration of Taipei), regulatory requirements (e.g. Swiss law), international standards (e.g. ISO)
- Database entry guidelines (e.g. BIMS)
- Safety guidelines for both donors, staff, and environment
- Facility management and maintenance guidelines
- The reporting and documentation of non-conformities (e.g. non-compliance)

Example: DNA/RNA in a biological sample
- Aim: to ensure that DNA/RNA analytical results obtained at different time points are comparable
- Requirement: to comply with ISO 20387 defining validated sample processing procedures for the preservation of tissue DNA and RNA.
- QC-indicator: a minimal delta (e.g. to ensure elapsed time between sample collection and processing is less than 45 minutes)
- QC-Indicator result: Calculated elapsed time between sample collection and processing
- Documentation:
- Time-lapse less than 45 minutes. QC-Indicator compliance
- Time-lapse more than 45 minutes. Non-adherence to required QC-Indicator, and occurrence of non-conformity. Implementation of follow-up procedures (e.g. sample destruction)
Was muss ich befolgen?
Define the processes of your biobank. Focus on:
- Organizational Requirements (e.g. reference to biobank regulation)
- Resource requirements (e.g. qualified staff, facilities, BIMS)
- Sample workflow requirements
Establish risk-based QC-steps:
- Defined QC-Indicators that must be complied with in order to ensure the quality of your biobank
- In the event of non-conformity, plan applicable risk control-measures
According to your QC strategy:
- Document risks management procedures in a SOP/WI, or in a project/study relevant Risk Assessment Form
- Plan additional QC risk control-measures, such as:
- Internal biobank audits (e.g. SBP Quality Labels)
- Management reviews
Example of Biological Material (BM) QC-steps with defined QC-Indicators:
- Cell viability: minimum % of viable cells required for analysis
- Yield: minimum amount of total cells needed for diagnosis
- Volume: minimum amount of collected BM (e.g. blood or serum) needed for analysis
- Sterility: presence of non-contaminated cells

Examples of identified biobanking risks and the implementation of risk control-measures:
- Facility and equipment:
- Risks: freezer break-down, incorrect measurement of pipettes and scales, lack of processing solutions
- Risk control-measures: freezer emergency plan, regular calibration of measuring equipment, regular inventory checks
- Donor and staff safety:
- Risks: staff exposed to toxic chemicals, lack of donor consent
- Risk control-measures: staff trainings, implementation of safety procedures, and of informed consent procedures (e.g. documented in SOPs/WIs)
- Data security:
- Risk: accidental disclosure of data to the public, accidental deletion of data
- Risk control-measures: BIMS with access control and audit-trail
