Problem: You examine a 22-year-old woman of Asian ancestry. She has no presenting complaint. Hemogram results are as follows: Hgb = 9.1 g (normal 12 to 14 g) Hct = 28% (normal 36% to 43%) RBC = 5.6 million mm3 (normal 4.2 to 5.4 million mm3) MCV = 68 fL (normal 81 to 96 fL) MCHC = 33.2 g/dL (normal 31 to 37 g/dL) RBC distribution width (RDW) = 13% (normal ≤15%). Reticulocytes = 1.5% (normal 1% to 2%).
This is most consistent with the laboratory assessment of:
