Test Overview

Test Methodology

Immunodiffusion

Test Usage

Tests are performed with standardized antigens of A. flavus, A. niger and A. fumigatus. Positive results, represented by one or more precipitin lines, are indicative of fungus ball, allergic bronchopulmonary aspergillosis (ABA), or invasive aspergillosis. Generally, the finding of 3-4 bands will indicate either fungus ball or ABA, with many cases of invasive aspergillosis requiring serum concentration for demonstration of precipitin lines.

Reference Range

Negative

* Reference ranges may change over time. Please refer to the original patient report when evaluating results.
