Irena Srebotnik Kirbis, PhD, is a Biomedical Scientist and Research Associate at the Institute of Pathology, Faculty of Medicine, University of Ljubljana, Slovenia. Her professional background includes cytopathology practice at the Institute of Oncology Ljubljana, with expertise in immunocytochemistry, sample processing, and quality improvement.
Her current work focuses on the optimized use of immunocytochemistry in cytology. She has served as Slovenia’s representative in the European Advisory Committee of Cytotechnology (EACC) since 1997 and as an assessor in two external quality programmes for cytology: the United Kingdom National External Quality Assessment Service (UK NEQAS) for Immunocytochemistry since 2004, and UK NEQAS Cellular Pathology Techniques (CPT) since 2014 and has authored several peer-reviewed publications.
Brief Description
This session demonstrates how even scarce cytology samples can be effectively used for immunocytochemistry (ICC), emphasizing rapid turnaround, diagnostic reliability, and the potential to support minimally invasive, timely clinical decision-making.
Learning Objectives
- Compare cytology sample processing methods, including their advantages and limitations, and apply best practices to ensure optimal specimen quality for timely and accurate diagnosis.
- Differentiate immunocytochemistry (ICC) and immunohistochemistry (IHC), including their similarities, differences, and appropriate clinical applications.
- Evaluate the challenges of cytology sample processing for ICC in the context of rapid diagnostic workflows (including ROSE), and justify the need for dedicated validation and optimization strategies.
- Apply quality assurance principles in ICC to achieve reliable and reproducible results, supporting accurate diagnosis, personalized treatment decisions, and minimally invasive patient care.
