How is thalassemia diagnosed with Hb electrophoresis?

If thalassemia is still suspected, a hemoglobin electrophoresis may help diagnose the condition. The hemoglobin electrophoresis with beta thalassemia trait usually has reduced or absent HbA, elevated levels of HbA2, and increased HbF.

Why can’t you diagnose alpha thalassemia on electrophoresis?

Hemoglobin analysis by electrophoresis can confirm the diagnosis by demonstrating the presence of HbH. Hemoglobin electrophoresis may not detect the low levels of Hb H in Hb HCS, in which case molecular testing may be necessary.

Can Hb electrophoresis detect alpha thalassemia?
