Hemoglobin Electrophoresis Results for Thalassemia Diagnosis - Cardiology

Understanding hemoglobin electrophoresis results is crucial for diagnosing thalassemia, particularly in the context of a family history of the condition. Thalassemia, commonly referred to as Mediterranean anemia, is a genetic blood disorder characterized by reduced hemoglobin production. The two main types are alpha-thalassemia and beta-thalassemia, each associated with different genetic mutations affecting hemoglobin chains.

In your case, the hemoglobin electrophoresis results show the following:
- Hb-A1: 91.6%
- Hb-A2: 5.5%
- Hb-F: 2.9%
- Hb-H: 0%
- Hb-BART'S: 0%
- Hb-S: 0%
To interpret these results, it’s important to understand the significance of each hemoglobin component:
1. Hb-A1: This is the normal adult hemoglobin, and a high percentage (like your 91.6%) indicates that the majority of your hemoglobin is functioning normally.

2. Hb-A2: This variant is typically present in small amounts (usually less than 3.5% in normal individuals). Your level of 5.5% is elevated, which can be indicative of beta-thalassemia trait. In beta-thalassemia, the body compensates for the reduced production of beta-globin chains by increasing the production of Hb-A2.

3. Hb-F (Fetal Hemoglobin): This is the hemoglobin present in fetuses and newborns. A normal adult level is typically less than 2%, so your level of 2.9% is slightly elevated but not significantly high.

4. Hb-H and Hb-BART'S: These are forms of hemoglobin that are typically associated with alpha-thalassemia. The absence of these forms in your results suggests that alpha-thalassemia is less likely.

5. Hb-S: This is the sickle cell hemoglobin, and your result of 0% indicates that you do not have sickle cell disease.

Given your family history of thalassemia, particularly with your sister being diagnosed with moderate beta-thalassemia, your results suggest that you may have a beta-thalassemia trait. This condition is often asymptomatic and does not typically require treatment, but it is important for family planning and understanding potential risks for offspring.

In conclusion, while your hemoglobin electrophoresis results do not definitively diagnose you with thalassemia, they do indicate a possibility of beta-thalassemia trait due to the elevated Hb-A2 level. It is advisable to discuss these results with your healthcare provider or a hematologist, who can provide further insights and possibly recommend genetic testing for a more definitive diagnosis. Additionally, they can guide you on any necessary follow-up or management strategies based on your specific situation and family history.
