My niece went for a routine check-up, and was referred to a Hematologist. Her CBC includes the following abnormal results: she s leukocytopenic (1.5), her Hgb (2.98) and HCT (8.8) are both low and she has thrombocytopenia (89), her RBC is also borderline low (2.98) ( however are normocytic and normochromic (MCV 89.9, MCHC 32.8). She s slightly fatigue, slightly feverish. There are no early cell lines (blasts or any precursors) on her differential. What could cause these results?
