Summary of lab results during the first and second hospital admissions.

Lab test	Normal range	First admission (pancytopenia)	Second admission (AIHA)
White blood cells	4.8–10.8 t/cmm	2.5	7.6
Hemoglobin	14–18 g/dL	9	7
MCV	80–94 fL	89.5	94.9
RDW	11.5–14.5%	15.9	22.5
Platelets	130–400 t/cmm	80	248
Reticulocyte count	0.5–1.5%	1	10.5
LDH	98–192 IU/L	193	478
Total bilirubin	0.2–1.5 mg/dL	2	3.6
Direct Coombs test	Negative	Negative	Positive (IgG)
