This test is ideal if you've been exposed to black mold (Stachybotrys chartarum) in your home or workplace and want to know if your immune system has responded to it. It's especially useful if you live or work in a water-damaged building and are experiencing unexplained respiratory symptoms, allergies, or chronic health issues that started after mold exposure. Many people use this test to confirm whether their symptoms are related to black mold and to track their immune response over time.
How should I prepare for this test?
No special preparation is typically required for this antibody test. You don't need to fast, and you can take your regular medications unless specifically instructed otherwise by your healthcare provider. It's helpful to note when and where your mold exposure occurred, as this context can help interpret your results.
What's included in this test?
This test measures IgG antibodies specific to Stachybotrys chartarum/atra (also known as black mold). IgG antibodies indicate that your immune system has encountered this mold and mounted a response, which can help confirm past or ongoing exposure. Elevated antibodies may explain why you experience allergy-like symptoms when exposed to moldy environments, even after the initial exposure has passed.
What happens after I get my results?
You'll receive detailed doctor notes in simple language explaining what your antibody levels mean and whether your immune system has responded to black mold exposure. These notes include personalized recommendations like environmental remediation steps, immune support strategies, and whether you should consult an allergist or environmental medicine specialist. You'll also get the standard lab report and can track your antibody levels over time using our trends feature to see if levels decrease after mold remediation or if re-exposure occurs.
When will I get my results?
Results are typically available within 5-7 business days after your sample reaches the lab. You'll receive an email notification when your results are ready to view in your secure online account, along with the doctor notes explaining what your antibody levels mean.
Who should consider getting this test?
This test is important for anyone who lives or works in a building with known water damage, visible black mold, or a musty odor. It's especially useful for people experiencing unexplained respiratory issues, chronic coughing, sinus problems, headaches, or fatigue that seem linked to their environment. If you're considering mold remediation or have recently completed it, this test can help assess your exposure level and track recovery.
What symptoms indicate I may need this test?
Common symptoms of black mold exposure include persistent coughing, wheezing, nasal congestion, throat irritation, and watery or itchy eyes. You may also experience headaches, fatigue, difficulty concentrating, or skin rashes that worsen when you're in the affected building and improve when you leave. If these symptoms started or worsened after water damage in your home or workplace, this test can help confirm if black mold is a factor.
How can I reduce my exposure to black mold?
The most important step is identifying and fixing any water leaks or moisture problems in your home, as black mold grows on wet cellulose materials like drywall and ceiling tiles. Use dehumidifiers to keep indoor humidity below 50%, ensure proper ventilation in bathrooms and kitchens, and promptly clean up any water spills or flooding. If you have significant mold growth, professional remediation is often necessary, as disturbing mold can release more spores into the air.
What does it mean if my IgG antibodies to black mold are elevated?
Elevated IgG antibodies indicate that your immune system has been exposed to black mold and has created a memory response to it. This means you've had significant exposure in the past or are currently exposed, and your body recognizes this mold as a potential threat. When you encounter black mold spores again, your immune system may quickly produce allergy symptoms even with minimal exposure, which explains why some people become increasingly sensitive to mold over time.
How often should I retest my black mold antibodies?
If you've recently moved out of a moldy environment or completed mold remediation, consider retesting in 3-6 months to see if antibody levels are decreasing, which indicates reduced exposure. If you continue living or working in the same environment, retesting every 6-12 months can help monitor whether exposure is ongoing or if remediation efforts have been successful. If you develop new symptoms or discover additional water damage, earlier retesting may be helpful.

What this means
Your IgG antibodies to black mold are elevated, indicating that your immune system has been exposed to Stachybotrys and has created a memory response. This confirms past or ongoing exposure and may explain why you experience allergy-like symptoms when in moldy environments. Elevated antibodies can persist for months or years after exposure.
Recommended actions
Identify and remediate any water damage or visible mold in your home or workplace
Use HEPA air purifiers in frequently occupied rooms to reduce airborne mold spores
Support your immune system with adequate sleep, stress management, and a nutrient-rich diet
Consider retesting in 3-6 months after remediation to monitor antibody levels
* Regular blood test results (e.g., CBC) typically start arriving the next business day after sample collection. More complex tests, such as hormone panels, may take up to 10–15 business days due to their complexity.
