The specific hemoglobin (Hb) that is high in thalassemia depends on the type of thalassemia.
Here's a breakdown based on the reference provided:
-
Beta-Thalassemia Major: Patients usually have larger percentages of HbF (fetal hemoglobin) and HbA2, and absent or very low HbA.
-
Beta-Thalassemia Minor: Patients usually have a mild elevation of HbA2 and a mild decrease of HbA.
-
Alpha-Thalassemia: HbH is a less common form of hemoglobin that may be seen in some cases.
In summary, HbF and HbA2 can be elevated in Beta-Thalassemia Major, HbA2 can be mildly elevated in Beta-Thalassemia Minor, and HbH may be present in some cases of Alpha-Thalassemia.
