Area of Science:

  • Bioanalytical Chemistry
  • Pharmacokinetics
  • Laboratory Automation

Background:

  • Routine toxicokinetic (TK) studies require efficient and accurate sample preparation.
  • Current methods can be prone to errors and may impact data quality.
  • A novel approach integrating 2D barcode processing and automated supported liquid extraction (SLE) was developed.

Purpose of the Study:

  • To introduce and validate a new bioanalytical sample preparation workflow.
  • To enhance efficiency, reduce errors, and improve data quality in TK sample analysis.
  • To assess the suitability of this methodology for routine bioanalytical support.

Main Methods:

  • Implementation of 2D barcode processing for sample tracking and management.
  • Utilization of fully automated supported liquid extraction (SLE) for sample preparation.
  • Validation of the automated SLE method for determining drug concentrations.

Main Results:

  • The automated SLE method was successfully validated.
  • Over 500 unknown samples were analyzed using 2D barcode processing.
  • Inter-day precision and accuracy were within 10% and 7.3%, respectively, based on 291 quality control samples.

Conclusions:

  • The combined use of 2D barcodes and automated SLE offers a novel logistical approach.
  • This methodology demonstrates significant potential for routine bioanalytical support of TK studies.
  • The enhanced workflow improves efficiency and data reliability in toxicokinetic analysis.
