Prevent Pre-Analytical Errors in Your Laboratory: How Full Sample Traceability Improves Workflow

Every day, laboratories face a complex journey for each sample. Pre-analytical errors during this phase can create major operational and quality issues if not properly managed.

Pre-Analytical Errors: Challenges in Modern Laboratory Workflows

Pre-Analytical Errors in Laboratory Processes

Around 60–70% of laboratory errors originate in the pre-analytical phase, making it one of the most critical — and vulnerable — parts of the diagnostic process. This phase includes every step before analysis, such as:

  • tube labeling and preparation
  • patient sample collection
  • transportation and logistics
  • sample reception at the laboratory

Each stakeholder — nurses, phlebotomists, couriers, and lab staff — operates within their own constraints. This leads to inconsistencies, delays, and missing information.

Hidden Complexity in the Pre-Analytical Phase

Even highly standardized labs often struggle with manual documentation, untracked handovers, and limited visibility during transport.

To understand the root causes in depth, learn more about the hidden complexity of pre-analytics.

Implementing Solutions to Prevent Pre-Analytical Errors

To successfully adopt digital traceability, laboratories should focus on:

Platform Integration

Choose a solution that integrates easily with your existing LIS, courier systems, and collection sites.

Real-Time Data Capture

Ensure that every sample movement — from pickup to reception — is automatically captured.

Staff Training

Provide simple, role-based training so each team member benefits from digital visibility.

Measuring ROI

Track KPIs such as error rate reduction, turnaround time, and admin hours saved.
