A 28-year-old man presents with chronic cough and
sputum production. He requires about four courses of
antibiotics per year. He has a history of frequent res-
piratory infections as o child including chronic sinusi-
tis, which has required several surgical drainage
procedures. A chest CT shows thickening and dilotu-
tion of peripheral airways in the lower lobes compat-
ible with bronchiectosis. He is married but has no
children. He works in a grain-storage facility as a
manager. Your evaluation would include all of the
following studies except:
A. Aspergillus precipitins
B. Serum immunoglobulin levels
C. Nasal mucosal biopsy with electron microscopy
D. Sweat chloride level
E. Serum protein electrophoresis
