INTERPRETATION
----------------------------
Consider IRON DEFICIENCY ANEMIA
Peripheral blood smear clues may include anisocytosis, poikilocytosis, and elliptocytosis.
CBC clues may include increased RDW and thrombocytosis.
Consider ANEMIA OF CHRONIC DISEASE
Peripheral blood smear clues may include unremarkable (usually), rouleaux formation, myelophthisis.
CBC clues may include normal RDW.
Usual causes of ANEMIA OF CHRONIC DISEASE may include Temporal arteritis, Rheumatoid arthritis, Chronic inflammation, or Chronic infection.
Unusual causes of ANEMIA OF CHRONIC DISEASE may include Hodgkin lymphoma, Renal cell carcinoma, Castleman disease, or Myelofibrosis.
Consider THALASSEMIA
Peripheral blood smear clues may include polychromasia, target cells, and basophilic stippling.
CBC clues may include normal or elevated RBC count and normal or elevated RDW.
Obtain hemoglobin electrophoresis.
Consult hematologist.
Consider ANEMIA DUE TO BLOOD LOSS
Peripheral blood smear clues may include polychromasia.
CBC clue is that it is usually unremarkable.
Identify/address causes of blood loss.
Consider IRON DEFICIENCY ANEMIA
Peripheral blood smear clues may include anisocytosis, poikilocytosis, and elliptocytosis.
CBC clues may include increased RDW and thrombocytosis.
Consider B12 DEFICIENCY ANEMIA
Peripheral blood smear clues may include anisocytosis and dimorphic RBCs.
CBC clues may include increased RDW.
Consider FOLATE DEFICIENCY ANEMIA
Peripheral blood smear clues may include anisocytosis and dimorphic RBCs.
CBC clues may include increased RDW.
Consider ANEMIA OF RENAL DISEASE
CBC clues may include normal RDW.
Consider AUTOIMMUNE HEMOLYTIC ANEMIA
CBC clues may include normal or elevated RDW, thrombocytosis.
Consult hematologist.
Consider HEREDITARY SPHEROCYTOSIS
CBC clues may include normal or elevated RDW, thrombocytosis.
Consult hematologist.
Consider HEMOLYTIC ANEMIA
Consult hematologist.
Consider DISSEMINATED INTRAVASCULAR COAGULATION (DIC)
Consult hematologist.
Consider VALVULAR HEMOLYSIS
Urinary Hemosiderin Test may be helpful.
Consult specialist to identify/address valvular concerns as appropriate.
Consider THROMBOTIC THROMBOCYTOPENIA/HEMOLYTIC UREMIC SYNDROME
CBC clues may include normal or elevated RDW, thrombocytopenia.
Consult hematologist.
Consider HEMOLYTIC ANEMIA
Consult hematologist.
Consider DRUG-RELATED MACROCYTIC ANEMIA
Peripheral blood smear clues may include oval macrocytes.
CBC clues may include increased RDW and marked or mild macrocytosis.
Adjust/discontinue medication in collaboration with prescriber if possible/appropriate.
Consider B12 DEFICIENCY ANEMIA
Peripheral blood smear clues may include oval macrocytes, hypersegmented neutrophils.
CBC clues may include increased RDW, marked or mild macrocytosis.

CBC clues may include increased RDW, marked or mild macrocytosis.
Consider MYELODYSPLASTIC SYNDROME or OTHER PRIMARY BONE MARROW DISORDER
Peripheral blood smear clues may include dimorphic RBCs, pseudo Pelger-Huet anomaly cells, oval macrocytes.
CBC clues may include increased RDW.
Consult hematologist.
Consider MYELODYSPLASTIC SYNDROME.
