Differential Diagnosis

The provided lab results indicate a 0.04-year-old male patient with various blood test results. Based on these results, the following differential diagnoses can be considered:

• Single Most Likely Diagnosis
  • Anemia: The patient's hemoglobin level is 9.63 g/dL, which is below the normal range (11.5-14.5 g/dL). The mean corpuscular volume (MCV) is 78 fL, indicating microcytic anemia. The red cell distribution width (RDW) is 30-35 g/dL, which is within the normal range. The patient's age and low hemoglobin level suggest anemia as the most likely diagnosis.
• Other Likely Diagnoses
  • Infection: The patient's white blood cell count is 6.00 x 10^9/L, which is within the normal range. However, the neutrophil percentage is 60.3%, and the lymphocyte percentage is 28-32%, which may indicate a mild infection.
  • Dehydration: The patient's sodium level is 136 mmol/L, which is within the normal range. However, the potassium level is 5.1 mmol/L, which is slightly elevated. This may indicate mild dehydration.
• Do Not Miss Diagnoses
  • Sepsis: Although the patient's white blood cell count is within the normal range, sepsis is a life-threatening condition that should not be missed. The patient's age and low hemoglobin level increase the risk of sepsis.
  • Congenital Disorders: The patient's age and low hemoglobin level may indicate a congenital disorder, such as thalassemia or sickle cell disease. These conditions require prompt diagnosis and treatment.
• Rare Diagnoses
  • Leukemia: The patient's white blood cell count is within the normal range, but the presence of blasts (0.12%) may indicate a rare diagnosis such as leukemia.
  • Bone Marrow Failure: The patient's low hemoglobin level and normal white blood cell count may indicate bone marrow failure, which is a rare condition in infants.
