Table 5.12 O Diagnostic Clues for the Thalassemic Conditions

If you are suspecting the two- or three-gene deletion alpha thalassemic state

• The MCVs are much lower than in IDA

• RDW is much more severe in alpha thalassemias

If you suspect the silent carrier alpha thalassemic state

• MCV is in normal or low-normal range

• Presence of elliptocytes on the smear is an indicator If you suspect beta thalassemia major state

• High numbers of nRBCs on smear

• Presence of targets, fragments on smear

• Microcytosis and hypochromia

• Hgb F is major hemoglobin on electrophoresis

If you suspect beta thalassemia minor state

• RBC count is elevated

• Microcytosis and hypochromia

• May see basophilic stippling, targets on smear
