Antibody to Aspergillus niger (Serum) - Immunoassay

What Does This Test Measure?

The test detects the presence of antibodies specific to *Aspergillus niger*, a common mold found in soil and decaying organic matter. If you’ve been exposed to this mold, your immune system may produce these antibodies over time. This does not directly measure active infection but indicates prior exposure or immune response.

Why Might You Need This Test?

Your healthcare provider may recommend this test if you have symptoms like persistent cough, fever, or lung issues—especially if you’ve lived in an area with high mold exposure, have a weakened immune system, or have a history of fungal infections.

How Is the Test Performed?

A blood sample is drawn from a vein in your arm. The sample is sent to a lab, where antibodies to *Aspergillus niger* are measured using an immunoassay method. Results are typically available within a few days.

What Do the Results Mean?

Positive results suggest your body has recognized *Aspergillus niger* antibodies, possibly from past exposure. However, they do not confirm an active infection. Negative results mean no detectable antibodies were found, but this does not rule out past exposure.
