From Hemoglobin to Beta-Cell Function: Practical Challenges, Standardization, and Clinical Use of HbA1c and C-Peptide Testing

Thursday, July 30
10:15 – 11:15 a.m.
Exhibit Hall Theater 1
Presented by Tosoh Bioscience Inc.

Overview

This workshop explores the evolving landscape of diabetes diagnostics, beginning with the importance of modern biomarkers. It provides a practical review of HbA1c testing, including method differences, standardization efforts, and the impact of hemoglobin variants. The session also examines the clinical role of C-peptide and current challenges in assay standardization. The program concludes with an integrated view of how these markers can be used together and a look at future directions in diabetes assessment.

Outcome

1. Understand the strengths and limitations of HbA1c methods, including how hemoglobin variants can affect result reliability
2. Describe the clinical utility of C-peptide and recognize key issues in assay standardization
3. Apply an integrated perspective on HbA1c and C-peptide testing to support more informed decision-making in diabetes assessment and future diagnostic strategies
