Area of Science:

  • Clinical immunology
  • Flow cytometry applications

Background:

  • Conventional basophil activation testing (BAT) is labor-intensive and hinders standardization for clinical use.
  • A programmatic, data-driven approach is needed to improve BAT analysis efficiency.

Purpose of the Study:

  • To develop and implement an automated, programmatic analysis for flow cytometry-based basophil activation testing (BAT).
  • To enhance objectivity and throughput in clinical BAT for allergy diagnostics.

Main Methods:

  • Utilized the BÜHLMANN FlowCAST® assay with peripheral blood from peanut-allergic patients.
  • Employed Bioconductor and R for programmatic analysis of basophil activation markers (CCR3, CD63).
  • Validated programmatic basophil identification against manual gating and compared reproducibility.

Main Results:

  • Achieved 91.5% success rate in BAT analysis across 269 experiments (7,166 tests).
  • Estimated a net labor saving of 1340 minutes for a skilled operator.
  • Demonstrated high correlation between programmatic and manual gating (R=0.96 vs. R=0.84), with only 2% significant differences.

Conclusions:

  • Introduced a novel, data-driven flow cytometry platform for objective, high-throughput clinical basophil activation analysis.
  • The developed approach significantly improves efficiency and standardization potential for BAT.
