Anemia
|
Decreased RBC Count &/or Hgb & Hct
|
|
Three Categories of Anemia
|
1. Normocytic, Normochromic
(MCV: 80-100 fl) (MCHC: 32-36%) 2. Microcytic, Hypochromic (MCV: <80 fl) (MCHC: <32%) 3. Macrocytic, Normochromic (MCV: >100 fl) (MCHC: 32-36%) |
|
Normocytic, Normochromic
|
Aplastic Anemia
Hereditary Membrane Defects Enzyme Defects Hemoglobinopathies Mechanical Trauma Immune Hemolytic Anemia PNH |
|
Aplastic Anemia
(Normocytic, Normochromic) |
Pancytopenia
*Retic count decreased *Bone marrow hypocellular Erythropoietin levels increased |
|
Membrane Defect
(Normocytic, Normochromic) |
(Hereditary Spherocytosis)
*Abnormal red cell morphology (target cells, spherocytes, stomatocytes, ovalocytes) Retic count increased *Osmotic fragility test increased or decreased |
|
Enzyme Defect
(Normocytic, Normochromic) |
(Glucose-6-phosphate dehydrogenase deficiency)
Abnormal red cell inclusions (Heinz bodies) *G6PD or Pyruvate Kinase level decreased |
|
Hemoglobinopathy
(Normocytic, Normochromic) |
**Sickle cell anemia:
Sickle cells *Retic count increased *sicklesol test positive *Hemoglobin electrophoresis shows presence of hemoglobin S **Hgb C disease: Hemoglobin C crystals and target cells on peripheral smear Hemoglobin electrophoresis shows presence of hemoglobin C |
|
Immune Hemolytic Anemia
(Normocytic, Normochromic) |
*Spherocytes of peripheral smear
DAT positive |
|
Mechanical Trauma
(Normocytic, Normochromic) |
*Schistocytes on peripheral smear
|
|
PNH (Paroxysmal nocturnal hemoglobinuria)
(Normocytic, Normochromic) |
Sugar water test
Ham's test positive |
|
Microcytic, Hypochromic
|
Iron Deficiency Anemia
Thalassemias Anemia of chronic disorders Lead poisoning |
|
Iron Deficiency Anemia
(Microcytic, Hypochromic) |
*Ferritin decreased
*Serum iron levels decreased *% saturation decreased *TIBC increased Retic count decreased *RDW increased |
|
Thalassemias (minor)
(Microcytic, Hypochromic) |
*Iron studies normal
*RDW normal *Red count normal or increased *Hemoglobin electrophoresis abnormal with increased A2 or F |
|
Anemia of Chronic Disorders
(Microcytic, Hypochromic) (May also be Normocytic, Normochromic) |
*Serum Fe decreased
*TIBC decreased *% saturation decreased *Bone marrow demonstrates an increase in storage iron |
|
Lead Poisoning
(Microcytic, Hypochromic) |
Increased blood lead levels
Basophilic stippling Cabot rings in RBCs |
|
Macrocytic, Normochromic
|
Megaloblastic Anemias
(B12 deficiency, Folate deficiency) |
|
B12 deficiency
(Macrocytic, Normochromic) |
*B12 levels decreased (neuro probs)
*Schillings test abnormal *Ab to intrinsic factor positive if due to Pernicious anemia *Hypersegs *tear cells |
|
Folate Deficiency
(Macrocytic, Normochromic) |
*Folate levels decreased
*Schillings test normal *Hypersegs *tear cells |
|
Iron Deficiency Anemia vs. Thalassemia Minor
|
Both are microcytic, hypochromic. IDA has a deficiency of iron leading to decreased production of heme which is needed to make hemoglobin. In the thalassemias there is a decreased production of globin chains which also are needed to make hgb.
