Modular robotic workcell for coagulation analysis.

Area of Science:

• Clinical Diagnostics
• Laboratory Automation
• Robotics in Healthcare

Background:

• Total laboratory automation (TLA) enhances lab efficiency and quality.
• Modular automation presents a smaller, more cost-effective alternative to TLA.
• A modular robotic preanalytical workcell for coagulation analysis was developed and clinically trialed.

Purpose of the Study:

• To engineer and evaluate a modular robotic preanalytical workcell for coagulation testing.
• To identify and address bottlenecks in manual preanalytical specimen processing.
• To quantify the efficiency gains of modular automation in a clinical setting.

Main Methods:

• Timing studies were conducted to assess manual preanalytical processing efficiency and identify bottlenecks.
• A modular robotic workcell was designed to mitigate identified processing delays.
• Specimen introduction into the workcell was designed to be flexible (manual, conveyor, or mobile robot).
• Clinical trials included further timing studies to evaluate the automated system's performance.

Main Results:

• Preanalytical processing time decreased from 18-107 minutes manually to 45-50 minutes with automation.
• The system demonstrated potential for further efficiency gains with high-quality, prelabeled specimens.
• Modular automation led to more consistent specimen processing times.

Conclusions:

• Modular automation offers a viable and efficient alternative to manual preanalytical processing for coagulation analysis.
• The robotic workcell successfully reduced processing times and variability.
• Further optimization is possible with improved specimen handling upstream.
