The black mold allergy test measures your immune system's response to Stachybotrys chartarum, a type of mold that can grow in damp indoor environments. It is ordered when a person has allergy-like symptoms—such as sneezing, coughing, or wheezing—that may be linked to mold exposure.
What it measures
- Specific IgE to Stachybotrys chartarum — The level of allergy antibody your immune system makes against this mold.
- Total IgE — A general measure of allergic tendency, sometimes included for context.
- Other mold IgEs (optional) — Tests for common molds like Aspergillus or Penicillium may be added to check for multiple sensitivities.
Who it is for
A doctor or allergist typically orders this test for people with ongoing respiratory or allergy symptoms and known or suspected mold exposure at home, work, or school.
Preparation
No fasting or special preparation is needed. You can eat and drink normally before the blood draw.
Results and what they mean
Results are reported as a numerical level or a class (for example, negative, low, or high) for each mold tested. A clinician interprets these results alongside your symptoms and history; a positive test alone does not confirm a diagnosis. This is general information, not medical advice.

Frequently asked questions
Does a positive result mean I have a mold allergy?
Not necessarily. A positive test shows your immune system has been exposed to the mold, but only a clinician can determine if it is causing your symptoms.
How accurate is this test?
Blood allergy tests are generally reliable, but they are not perfect. Results must be interpreted with your medical history.
Can I take this test if I am taking allergy medication?
Yes, but tell your clinician about all medications. Some drugs may affect test results.
What should I do if my result is positive?
Discuss the result with your clinician. They can help you understand what it means and whether any steps, like reducing mold exposure, are appropriate.
