"HISTORY:This one year-old boy had a history of increased listlessness and fatigue. Dietary history showed a heavy milk intake with little supplemental food.
PHYSICAL FINDINGS: Pale, chubby infant with no other pertinent physical findings.
LABORATORY RESULTS: hematocrit: 17.7% (nl: 37-48%), hemoglobin: 5.3 g/dl (nl: 13-17%), MCH: 19.5 (nl: 27-32 pg/RBC), MCHC: 30.0 (nl: 32-36%), MCV: 65 cu microns (nl: 86-98 cu microns/cell), RBC: 2.72, million/cu mm (nl: 3.5-5 million/cu), reticulocyte count: 1.7% (nl: 0.5-1.5%)
CLINICAL COURSE: A diagnosis was made and therapy started. On return visit 10 days later the following laboratory results were obtained: hematocrit: 20.8%, hemoglobin: 6.24 g/dl, RBC: 2.92 million/cu mm, reticulocyte count: 10%
