Sample

Blood draw or sample collection at a local center

An Aspergillus niger-specific IgE blood test measures antibodies the immune system may produce against spores of the mold Aspergillus niger, sometimes called black mold. It is a screening tool for suspected mold allergy, not a diagnosis on its own. Clinicians may order it when nasal, eye, or respiratory symptoms occur in damp or moldy environments, or when reviewing a mold allergy panel. Results are interpreted with symptom timing and exposure history.

• Aspergillus niger mold spore-specific IgE IgE antibodies directed against Aspergillus niger (black mold) spores; used to assess sensitization to this mold allergen.

• Nasal, eye, or respiratory symptoms in damp or moldy spaces
• Symptoms around soil, produce, or decaying plant material
• Known mold sensitivity when component-level testing is desired
• Evaluation as part of a mold or environmental allergy panel

• No fasting is required for most IgE allergy tests
• Tell the provider about antihistamines and other medications that may affect interpretation
• A single blood draw is collected; no special preparation is needed

Results are reported as a level of Aspergillus niger mold spore-specific IgE, often described as negative, low, moderate, or high. An elevated level may indicate sensitization to Aspergillus niger spores, but it does not confirm that this mold is causing symptoms and is not a test for infection. A negative result does not completely rule out allergy. Discuss results with a healthcare provider alongside your history.
