LabSage improves clinical laboratory AI by decoupling retrieval and reasoning, enhancing accuracy and compliance in regulated environments. This approach addresses context fragmentation in standard methods.

Area of Science:

  • Clinical Laboratory Science
  • Artificial Intelligence in Medicine
  • Regulatory Compliance

Background:

  • Clinical laboratories require strict adherence to Standard Operating Procedures (SOPs) within a regulated environment.
  • Standard Retrieval-Augmented Generation (RAG) methods struggle with context fragmentation, disrupting procedural dependencies in this domain.

Purpose of the Study:

  • To introduce LabSage, a novel domain-adapted framework designed to overcome the limitations of standard RAG in clinical laboratory settings.
  • To improve the accuracy and completeness of information retrieval for laboratory procedures.

Main Methods:

  • Developed LabSage, a framework employing structural-semantic decoupling with a hierarchical architecture.
  • Indexed compact search units for precision and dynamically retrieved expanded context units for completeness.
