Aspergillus fumigatus IgE             <0.35             kU/L    

Aspergillus fumigatus IgG             <46                mcg/mL

A. fumigatus Mix Gel Diffusion     Negative

 

The gel diffusion method was used to test this patient’s serum for the presence of precipitating antibodies (IgG) to the antigens indicated.  These antibodies are serological markers for exposure and immunological sensitization.  The clinical significance varies, depending on the history and symptoms.  This test was developed and its performance characteristics determined by Viracor-IBT Laboratories.  It has not been cleared or approved by the FDA.

 

Patients with allergic bronchopulmonary aspergillosis (ABPA) are expected to have the following serological features:

 

1)     A high total IgE of >500 IU/mL, unless patient is receiving corticosteroids.

2)     An elevated Aspergillus-specific IgE of class 4 or higher.

3)     Positive for Aspergillus-specific IgG.
