A New Perspective on HbA1c Evaluation ​

 
A holistic overview of hemoglobinopathies interactions with glycated hemoglobin

By M. Flamini, MSc as seen in the Medical Laboratory Observer​

Knowledge and awareness of thalassemia and hemoglobin variants affecting HbA1c measurements is essential. In this article, Marco Flamini emphasizes the need to evaluate hemoglobin variants that are coinherited with thalassemia and/or associated with elevated HbF. Ultimately, identifying the clinical status of the patient will lead to accurate result interpretation and better patient treatment decisions.

List of Hemoglobin Variants

list of variants brochure cover

Patient care is at the heart of what you do. We're here to help you serve clinicians and their patients. There are thousands of rare hemoglobin variants that could appear on your chromatograms. And since we know how important it is to identify unknown peaks and accurately analyze chromatograms, we've developed a list of hemoglobin variants that were run on the VARIANT II Beta Thalassemia Short Program.

This convenient list, organized by retention time, can be used as an educational tool to help when you are evaluating unfamiliar hemoglobin variant cases and considering further studies.
