Discussion

 

The intern orders a Fe study which reveal the following:

Serum Fe 20 ug/dL
Serum TIBC 400 ug/dl
Serum ferritin 10ug/L

The patient is discharged with Fe supplementation, but returns to the Emergency Department with minimal change in her symptoms. Her repeat CBC shows:

Hgb 8
Hct 24
WBC 3.8
MCV 112

  1. What would your differential diagnosis be now, and what additional tests would you order?


The peripheral smear is reviewed and reveals two six lobed PMNs in addition to macroovalocytes.
