Table 1

The patient had confirmed deficiencies in IgA, IgG2, and IgG4. Immunoglobulin levels are expressed in mg/dL with age-matched reference ranges provided.

Low albumin	No	Yes	No
IgG	1240 (639–1344 mg/dL)	2540** (767–1590 mg/dL)	1230 (614–1295 mg/dL)
IgG1	960 (422–1292 mg/dL)	1730** (341–894 mg/dL)
IgG2	14* (117–747 mg/dL)	171 (171–632 mg/dL)
IgG3	275** (41–129 mg/dL)	299** (18–106 mg/dL)
IgG4	5* (10–67 mg/dL)	13 (2–121 mg/dL)
IgA	11* (70–312 mg/dL)	<7* (69–309 mg/dL)	<7* (69–309 mg/dL)
IgM	151 (34–210 mg/dL)	591** (53–334 mg/dL)	125 (53–334 mg/dL)
IgE		6 (0–100 mg/dL)

Abnormally low levels. Abnormally high levels. Data are presented from 2005 (before IVIG therapy), 2011 (trough level during IVIG therapy at a time of hypoalbuminemia), and 2012 (trough level during IVIG therapy at a time of normal serum albumin).
