About this test
A Stachybotrys chartarum-specific IgE blood test measures antibodies the immune system may produce against spores of the mold Stachybotrys chartarum, sometimes called black mold and associated with water-damaged buildings. 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 a damp or water-damaged environment, or when reviewing a mold allergy panel. Results are interpreted with symptom and exposure history.
What this test measures
- Stachybotrys chartarum mold spore-specific IgE IgE antibodies directed against Stachybotrys chartarum mold spores; used to assess sensitization to this mold allergen.
Who this test may be right for
- Nasal, eye, or respiratory symptoms in a damp or water-damaged building
- Symptoms that improve away from a moldy indoor environment
- Known mold sensitivity when component-level testing is desired
- Evaluation as part of a mold or environmental allergy panel
Before your visit
- 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
Understanding your results
Results are reported as a level of Stachybotrys chartarum mold spore-specific IgE, often described as negative, low, moderate, or high. An elevated level may indicate sensitization to Stachybotrys chartarum spores, but it does not confirm that this mold is causing symptoms and is not a test for toxicity or infection. A negative result does not completely rule out allergy. Discuss results with a healthcare provider.
