How do I ensure my sample registration workflow with a laboratory information management system is compliant in a regulated lab?

To make a sample registration workflow in a regulated lab compliant, focus on documented process control, data integrity, traceability, access control, and validation. The exact requirements depend on your regulations (for example: GLP, GMP, GCP, ISO 17025, CLIA, CAP, 21 CFR Part 11, EU Annex 11, GDPR/HIPAA), but the core approach is similar.

1) Define the regulated process clearly

Create a written SOP for sample registration that covers:

• sample receipt and accessioning
• unique sample ID assignment
• required metadata capture
• chain of custody
• exception handling
• rejection criteria
• labeling rules
• storage conditions
• approval/release steps

Make sure the SOP matches how the LIMS is actually used.

2) Validate the LIMS workflow

The system and workflow should be validated for intended use:

• user requirements specification (URS)
• risk assessment
• functional testing / IQ OQ PQ as applicable
• testing of critical controls:
  • unique IDs
  • audit trails
  • role-based permissions
  • electronic signatures
  • date/time stamps
  • data retention
  • record locking after approval
• documented approval of validation results

3) Enforce data integrity principles

Use ALCOA+ principles:

• Attributable: every action tied to a user
• Legible: records readable and understandable
• Contemporaneous: recorded when the action happens
• Original: source data preserved
• Accurate: verified and controlled
• plus Complete, Consistent, Enduring, Available

In practice:

• no shared accounts
• automated audit trails
• controlled edits with reason for change
• preserve original values
• no manual re-entry unless controlled and checked

4) Control user access and permissions

Set role-based access so users can only do what their job allows:

• sample receiving staff can register, but not delete approved records
• supervisors can approve exceptions
• admins cannot alter regulated data without traceability
• periodic review of active accounts
• immediate removal of departed users
• strong password and MFA policies if applicable

5) Maintain chain of custody and traceability

Every sample should be traceable from receipt to final disposition:

• who received it
• when it was received
• condition on receipt
• where it was stored
• transfers between users or locations
• testing and disposition history

Use barcode labeling and scan-based workflows where possible to reduce transcription errors.

6) Standardize required fields and validations

Make mandatory fields for registration, such as:

• sample ID
• submitter/source
• collection date/time
• receipt date/time
• sample type/matrix
• storage condition
• test request / protocol ID
• acceptance/rejection status

Add validation rules:

• date logic checks
• controlled vocabularies
• format checks
• duplicate detection
• mandatory reason for deviations

7) Handle deviations and exceptions formally

If a sample arrives late, mislabeled, damaged, or incomplete:

• document the issue
• assess impact
• decide accept/reject/conditionally accept
• obtain required approval
• preserve the original record and rationale
• trend recurring problems through CAPA

8) Ensure audit trails and record retention

Your LIMS should automatically capture:

• who created/edited/viewed/approved records
• what changed
• when it changed
• why it changed, if required

Also define:

• retention periods
• archival and backup procedures
• disaster recovery
• retrieval testing for archived records

9) Train and qualify personnel

Train users on:

• SOPs
• LIMS use
• data integrity
• good documentation practices
• escalation paths for exceptions

Keep training records and periodic requalification if required.

10) Perform periodic review and monitoring

Compliance is ongoing. Review:

• audit trails
• open deviations
• access logs
• sample registration errors
• CAPAs
• system alerts
• backup/restore tests
• periodic review of validated state

11) Manage change control

Any changes to the workflow, templates, interfaces, or LIMS configuration should go through change control:

• impact assessment
• approval
• testing
• revalidation if needed
• SOP updates
• retraining

12) Align with applicable regulations

Examples:

• 21 CFR Part 11 / Annex 11: electronic records/signatures, audit trails, access control, validation
• ISO 17025: sample identification, handling, traceability, record control
• GMP/GLP: documented procedures, data integrity, change control, QA oversight
• CAP/CLIA: specimen identification, receipt, rejection criteria, documentation
• GDPR/HIPAA: privacy, access limitations, data minimization, retention

Practical checklist

A compliant sample registration workflow usually has:

• written SOPs
• validated LIMS configuration
• unique sample IDs
• barcode tracking
• mandatory metadata fields
• controlled user roles
• audit trail enabled and reviewed
• exception/deviation process
• training records
• change control
• backup/archival and recovery testing
• periodic internal audits

Best next step

Map your current workflow against:

1. applicable regulations
2. SOP requirements
3. LIMS configuration settings
4. validation evidence
5. training and audit records
