Sample accessioning in Clinical Labs: Best Practices and Procedures

In any lab, sample collection and management are important to lab operations. How accurately samples are labelled and tracked determines the efficiency of lab operations, and by extension, the quality of outcomes like diagnosis. In this connection, sample accessioning is the part of an activity that differentiates acknowledged samples from non-acknowledged samples, maintaining a clear segregation. It enables easy accessibility to lab personnel and adds another layer of quality checks before the processing stage.

Labs can also accept or reject samples in a suitable condition with strict sample accessioning practices, improving responsibility and compliance.

Best Practices in sample accessioning

sample accessioning involves the below procedures for the best results.

Accurate Labeling

Precise labeling and entry into a Laboratory Information Management System (LIMS) are essential. Each specimen receives a unique ID and date of receipt, enabling clear tracking and management throughout its lifecycle. Barcode tracking further assists in separating samples for tests that require multiple types, e.g. Blood Glucose, where both fasting and post-prandial samples are collected. LIMSs reduces errors and ensures that samples are correctly logged and easy to locate.

Barcoding Samples

Barcoding connects physical samples directly to the LIMS Sample Management System, allowing exact, electronic sample accessioning through distinct Sample IDs. Barcode make sample sorting and identification straightforward, organising them by date, patient, or location. The barcode label includes shortcodes, providing immediate access to patient and test information. Each ID is distinctively designed to effectively communicate relevant details.

Proper Handling

Carefully unpacking samples and following well plate management maintains accuracy during sample handling. Scrupulous pipetting and strict aseptic techniques keep the integrity of each sample, reducing contamination risks. Proper handling means samples are processed accurately, keeping the testing environment safe and clean and preserving sample quality.

Correct Storage

Proper temperature and volume are required to maintain sample integrity. Correct storage before and after the workflow prevents degradation or contamination, keeping samples remain viable for accurate testing. Each sample’s requirements are met, so it maintains its quality through every stage, supporting reliable and valid test results.

Standard Operating Procedures (SOPs)

SOPs provide structured guidelines that prevent errors in handling. They minimise risks of contamination and misplacement by defining best practices and quality standards. Consistently following SOPs reduces the likelihood of mistakes and the lab maintains high-quality results. The safety of lab personnel and samples is also covered.

Avoiding Errors

Mistakes can compromise results and delay patient care, so careful management at each stage is essential. By focusing on accurate handling, storage, and labeling, labs can prevent errors and provide reliable results. Continuous attention to detail means each sample is treated correctly, supporting timely and accurate testing.

Laboratory Information System (LIS/LIMS)

LIS or LIMS restricts data access to authorised users, tracking each entry and modification. Audit trails monitor any changes, ensuring compliance with regulatory guidelines and enhancing sample traceability.

HIPAA Compliance & Automation

Automation within sample management systems improves accuracy while ensuring compliance with HIPAA standards. This approach secures patient data and optimises workflows. Automating routine tasks also allows lab personnel to focus on critical analyses, reducing human error.

Advantages of sample accessioninging

sample accessioning directly impacts the efficiency of lab operations. It helps conduct various functionalities with ease and consistency.

• Sample accessioning makes outsourcing easier by accurately tracking samples across labs. It reduces mistakes and ensures reliable results when external help is needed.
• Home collections become more efficient for phlebotomists. They can access details, record times, and meet quality standards for a smooth sample collection.
• Automatic tracking of pre-analytical turnaround time (TAT) helps labs identify delays quickly, improving efficiency and eliminating the need for manual calculations.
• Lab systems can meet standards with sample archiving, which improves tracking, handles exceptions, and speedes up processes to maintain sample integrity.
• Automated notifications keep lab staff informed of important tasks. For example, new samples or test completions.
• Accessioning systems take care of compliance by accurately tracking and documenting samples, supporting audits and inspections. Labs can maintain accreditation with reliable results.

Advanced Procedures of Sample Tracking

1. Real-Time Tracking: Allows labs to monitor each sample's location and processing stage instantly.
2. Automated Quality Control: Systems can flag samples that don’t meet specific conditions (e.g., volume, temperature).
3. Equipment Compatibility Alerts: The software can flag samples incompatible with certain equipment, avoiding testing errors early.
4. Environmental Condition Logging: Systems can record and monitor conditions like storage temperature or humidity for each sample, providing detailed historical data.
5. Cross-Lab Coordination: For labs with multiple locations, accession systems facilitate easy data sharing, improving handling and processing continuity.

Further Action

Beyond these essential practices, nurturuing a culture of responsibility and precision among lab staff can further elevate sample handling standards. Training in the latest technology and techniques means that team members stay proficient at every stage of the sample journey. By prioritising continuous education and team commitment, labs create an environment where sample quality, regulatory adherence, and timely results become the norm, adding consistency and value to patient care.
