Neftaly: Ensuring Chain of Custody for Samples
At Neftaly, maintaining a secure and traceable chain of custody (CoC) is essential to the credibility, integrity, and admissibility of test results—particularly in forensic, clinical, and research environments. A well-managed chain of custody ensures that every sample is handled with accountability from collection to final analysis and reporting.
We implement stringent procedures to protect sample identity, prevent tampering or contamination, and uphold regulatory and legal standards.
???? What is Chain of Custody?
The chain of custody is the documented and unbroken process of tracking a sample’s possession, handling, transfer, and storage from its origin to its final destination. It ensures:
- Sample integrity and identity
- Traceability and accountability
- Legal admissibility of evidence
- Protection against loss, tampering, or contamination
????️ Neftaly’s Chain of Custody Process
✅ 1. Sample Collection
- Each sample is collected following approved protocols with clear labeling and unique identifiers.
- Samples are sealed in tamper-evident packaging immediately after collection.
- Collection personnel complete initial custody forms including date, time, collector name, and sample type.
✅ 2. Documentation and Tracking
- Every handoff of the sample is recorded in a Chain of Custody Form or system, detailing:
- Names and signatures of individuals involved
- Time and date of transfers
- Reason for transfer and condition of the sample
- Digital tracking systems (e.g., barcodes, LIMS) are used for enhanced traceability and audit readiness.
✅ 3. Secure Transport and Storage
- Samples are transported in secure, temperature-controlled containers with environmental monitoring where needed.
- Storage areas are access-controlled and monitored to ensure sample integrity until analysis.
- Detailed logs track storage conditions, retrieval times, and personnel involved.
✅ 4. Laboratory Receipt and Verification
- Upon receipt, samples are inspected for proper labeling, seal integrity, and condition.
- Any discrepancies (e.g., damaged seals or labeling issues) are documented and reported immediately.
- Samples are logged into the laboratory information system (LIS/LIMS) and assigned to authorized personnel.
✅ 5. Controlled Analysis and Access
- Only trained and approved staff are permitted to handle samples.
- Workflows are designed to prevent cross-contamination and maintain identity.
- All actions during testing are recorded in real time for traceability.
✅ 6. Post-Analysis Handling
- After testing, samples are either:
- Properly stored for re-analysis or long-term archiving, or
- Disposed of according to approved biosafety and environmental protocols.
- Final custody records are completed and stored securely for legal or regulatory review.
