What is a normal HbA2 level?

A normal HbA2 level is typically 2% to 3% (0.02 to 0.03) of the total hemoglobin.

Here's a breakdown of what that means:

• HbA2: Hemoglobin A2 is a minor type of hemoglobin found in red blood cells.
• Normal Range: The reference range for HbA2 is 2% to 3% (0.02 to 0.03) of the total hemoglobin.
• Significance: HbA2 levels are often measured to help diagnose and manage certain types of hemoglobinopathies, particularly beta-thalassemia trait.
