Differential Diagnosis

The patient's laboratory results show a hemoglobin level of 124 g/L, hematocrit of 0.39, RBC count of 4.08 x 10^12/L, ferritin level of 124 μg/L, and iron level of 8 μmol/L. Based on these results, the following differential diagnoses can be considered:

• Single Most Likely Diagnosis
  • Anemia of Chronic Disease: The patient's iron level is low, but the ferritin level is elevated, which is consistent with anemia of chronic disease. This condition is characterized by a decrease in iron availability due to chronic inflammation, despite adequate iron stores.
• Other Likely Diagnoses
  • Iron Deficiency Anemia: Although the ferritin level is elevated, the iron level is low, which could suggest iron deficiency anemia. However, the ferritin level is typically low in iron deficiency anemia.
  • Chronic Kidney Disease: The patient's hematocrit and RBC count are slightly low, which could be consistent with anemia of chronic kidney disease.
• Do Not Miss Diagnoses
  • Hemoglobinopathy: Although the patient's hemoglobin level is slightly low, it is essential to rule out hemoglobinopathies, such as thalassemia or sickle cell disease, which can have significant clinical implications.
  • Malignancy: Anemia can be a presenting feature of various malignancies, such as lymphoma or leukemia. Although the patient's laboratory results do not strongly suggest malignancy, it is crucial to consider this possibility.
• Rare Diagnoses
  • Porphyrias: These are a group of rare genetic disorders that can affect heme synthesis and cause anemia.
  • Sideroblastic Anemia: This is a rare condition characterized by the presence of ringed sideroblasts in the bone marrow, which can cause anemia and elevated ferritin levels.
