Mediterranean Anemia: Diagnosis and Further Testing - Cardiology

More Info

---

Mediterranean anemia, also known as thalassemia, is a genetic blood disorder characterized by the reduced production of hemoglobin, which can lead to anemia. The diagnosis of thalassemia typically involves a combination of blood tests, including complete blood count (CBC), hemoglobin electrophoresis, and sometimes genetic testing.
Based on the blood test results you provided, let's analyze the key parameters:
1. RBC (Red Blood Cell Count): Your RBC count is elevated at 6.23 million cells per microliter, which is higher than the normal range for adults. This can be indicative of a compensatory response to anemia or other underlying conditions.

2. HGB (Hemoglobin): Your hemoglobin level is 13.0 g/dL, which is within the normal range for adult females but on the lower end for males. In thalassemia, hemoglobin levels can vary, but they are often lower than normal.

3. HCT (Hematocrit): Your hematocrit level is 40.1%, which is also within the normal range.
4. MCV (Mean Corpuscular Volume): Your MCV is 64.4 fL, which is significantly lower than the normal range (80-100 fL). This microcytic anemia is a classic sign of thalassemia or iron deficiency anemia.

5. MCH (Mean Corpuscular Hemoglobin): Your MCH is 20.9 pg, which is also low, supporting the diagnosis of microcytic anemia.

6. MCHC (Mean Corpuscular Hemoglobin Concentration): Your MCHC is 32.4 g/dL, which is within the normal range.

7. Platelet Count: Your platelet count is 178, which is within the normal range.

8. WBC (White Blood Cell Count): Your WBC count is 5120, which is also within the normal range.

9. Serum Iron: Your serum iron level is 138 mcg/dL, which is within the normal range.

10. TIBC (Total Iron Binding Capacity): Your TIBC is 292 mcg/dL, which is also within the normal range.

11. Ferritin: Your ferritin level is 109 ng/mL, indicating adequate iron stores.


Interpretation:
The combination of low MCV and MCH with normal serum iron and ferritin levels suggests that iron deficiency is less likely. The elevated RBC count, along with the microcytic indices, raises the suspicion for thalassemia, particularly if there is a family history or ethnic background associated with the condition.


Diagnosis and Further Testing:
To confirm a diagnosis of Mediterranean anemia (thalassemia), further testing is recommended:
1. Hemoglobin Electrophoresis: This test separates different types of hemoglobin and can help identify abnormal hemoglobin variants associated with thalassemia.

2. Genetic Testing: If thalassemia is suspected, genetic testing can confirm the presence of mutations in the globin genes.

3. Reticulocyte Count: This test measures the number of young red blood cells in the blood and can indicate how well the bone marrow is responding to anemia.

4. Peripheral Blood Smear: A blood smear can provide additional information about the shape and size of red blood cells, which can be helpful in diagnosing thalassemia.


Conclusion:
Based on your results, while there are indicators that may suggest thalassemia, a definitive diagnosis cannot be made without further testing, particularly hemoglobin electrophoresis. It is essential to consult with a hematologist or a healthcare provider specializing in blood disorders for a comprehensive evaluation and appropriate management. If thalassemia is confirmed, the severity can be classified as mild, moderate, or severe based on the specific type and clinical presentation.
