## **TOSOH BIOSCIENCE-DIAGNOSTICS EMEA**

 

# Understanding Unstable Haemoglobins: Diagnosis and Clinical Manifestations

Tuesday Nov. 11th, 2025, 10:00 am GMT (11:00 am CET) 

This session will explore the rare but clinically significant group of haemoglobin variants known as **unstable haemoglobins**, which can lead to haemolysis, interfere with HbA1c measurements, and complicate diagnosis.

 

Dr. Marwah will share insights into the genetic mechanisms, laboratory features, and clinical presentations of variants such as **Hb Köln, Hb Zurich, Hb Bushwick** and more.

 

Whether you're a laboratory professional, clinician, or researcher, this webinar will deepen your understanding of how to detect and manage these complex cases.
