Thalassemia Screen
Thalassemia is characterized by an abnormal hemoglobin that is unusually fragile. The most common form of this is alpha-thalassemia minor, with an increase in hemoglobin A2. While this rarely is associated with clinical illness, it can have significance during pregnancy.

Hemoglobin electrophoresis showing elevated levels of hemoglobin A2 confirms thalassemia.

Normal Values*

Hemoglobin A2 2.5% - 4.0%

*These are general values taken from a variety of sources. The actual normal values may vary from lab to lab and from one type of testing protocol to another.
