2022年5月16日 · Macrocytic anemia is a blood disorder that happens when your bone marrow produces abnormally large red blood cells. These abnormal blood cells lack nutrients red blood cells need to function normally. Macrocytic anemia isn’t a serious illness but it can cause serious medical issues if left untreated.

The cause of macrocytic anemia is classified into one of the following categories, megaloblastic or nonmegaloblastic. Megaloblastic anemia is caused by deficiency or impairment of utilization of vitamin B12 or folate. Nonmegaloblastic anemia may be the result of liver dysfunction, alcoholism, myelodysplastic syndrome (MDS), or hypothyroidism.

2023年8月8日 · Macrocytic anemia can be caused by either a hypoproliferative disorder, hemolysis, or both. Thus, it is important to calculate the corrected reticulocyte count when evaluating a patient with macrocytic anemia. In hypoproliferative macrocytic anemia, the corrected reticulocyte count is <2%, and the MCV is greater than 100 fl.
Iron studies and hemolysis labs: If the reticulocyte count and chemistry panel are unrevealing, determine serum iron concentration, serum TIBC/transferrin, and serum ferritin concentration measured and transferrin saturation (TSAT) calculated to diagnose iron deficiency or ACD/AI.
