The mean erythrocyte hemoglobin concentration is the concentration of hemoglobin per liter of red blood cells and is often used as an indicator to diagnose and differentiate anemia. High mean erythrocyte hemoglobin concentration is often associated with megaloblastic anemia and myelodysplastic syndrome. 1. megaloblastic anemia: laboratory findings of megaloblastic anemia are often characterized by high mean erythrocyte hemoglobin concentration, increased mean erythrocyte hemoglobin content, and increased red blood cell volume, and patients can apply some folic acid and vitamin B12 supplements to correct the anemia. 2, myelodysplastic syndrome: When patients with myelodysplastic syndrome have anemia complications, laboratory test results will show high average red blood cell hemoglobin concentration, and then red blood cells can be transfused to increase the number of red blood cells to improve anemia and correct the average red blood cell hemoglobin concentration in the blood. In daily life, you can eat foods rich in folic acid, such as nuts, beans, vegetables and fruits, and foods rich in vitamin B12, such as animal liver, milk, eggs, etc.
