Aspergillus niger IgG

About

Aspergillus niger IgG is an antibody produced by the body a few weeks after infection with the fungus Aspergillus niger. This species of Aspergillus causes a disease called 'black mould' on fruit and vegetables, which can contaminate food. Much more uncommonly, it can lead to aspergillosis in humans, however this is more commonly associated with Aspergillus fumigatus.

What might a high result mean?

Levels of Aspergillus niger IgG represent immunity to infection with the fungus. This means that those possessing IgG have previously been infected by Aspergillus niger and are immune to subsequent infections.
