What's this test for?

This test is ideal if you're experiencing unexplained respiratory issues like persistent coughing, wheezing, nasal congestion, or skin irritation that might be triggered by mold exposure. It specifically checks for IgG antibodies to Rhizopus nigricans, a common black bread mold found in damp environments, helping you identify if this particular mold is contributing to your symptoms. Many people use this test when they suspect their home or work environment has mold issues affecting their health.

What happens after I get my results?

You'll receive detailed doctor notes in simple language explaining what your IgG antibody levels mean and whether Rhizopus nigricans sensitivity is contributing to your symptoms. These notes include personalized recommendations like environmental changes, avoidance strategies, air purification suggestions, or whether you should consider seeing an allergist. You'll also get the standard lab report and can track your antibody levels over time using our trends feature to see if your interventions are reducing your sensitivity.

What's included in this test?

This test measures Allergen Specific (m11) IgG Rhizopus nigricans antibodies. IgG antibodies indicate delayed immune responses to mold exposure, which can help explain chronic or recurring symptoms like congestion, coughing, fatigue, or skin issues. This specific measurement helps you pinpoint whether this particular mold species is triggering your immune system and causing your symptoms.

How should I prepare for this test?

No special preparation is needed for this allergy test. You don't need to fast, and you can take your regular medications unless otherwise directed by your healthcare provider. It's a simple blood draw that can be done any time of day, making it convenient to fit into your schedule.

When will I get my results?

Most IgG allergy testing results are typically available within 3-5 business days after your blood sample reaches the laboratory. You'll receive an email notification when your results are ready to view in your secure online account, along with the detailed doctor notes explaining what your results mean.

Who should consider getting this test?

This test is particularly useful for people who have persistent respiratory symptoms, recurring sinus infections, or unexplained skin issues that worsen in damp environments. It's also helpful for those who've found visible mold in their home or workplace, have a history of water damage in their living space, or notice symptoms improve when away from certain environments. Anyone suspecting mold sensitivity who wants to identify the specific type of mold causing problems should consider this test.

What symptoms indicate I may need this test?

Common symptoms suggesting Rhizopus mold sensitivity include chronic nasal congestion, persistent cough, wheezing or difficulty breathing, frequent sinus infections, and itchy or watery eyes. You might also experience skin rashes, headaches, fatigue, or brain fog that seems worse in humid or damp environments. If your symptoms improve when you're away from home or certain buildings, mold sensitivity could be the cause.

How can I reduce mold exposure in my environment?

Start by controlling moisture levels in your home by fixing leaks, using dehumidifiers to keep humidity below 50%, and ensuring proper ventilation in bathrooms and kitchens. Regularly clean and inspect areas prone to dampness like basements, bathrooms, and around windows. Use HEPA air purifiers to filter mold spores from indoor air, and consider professional mold remediation if you discover significant mold growth. Discarding moldy food promptly and keeping your home clean and dry are essential preventive steps.

What is Rhizopus nigricans and why does it matter?

Rhizopus nigricans is a common black mold species often called bread mold because it frequently grows on bread, fruits, and vegetables. It thrives in warm, moist environments and releases spores that can become airborne and trigger allergic reactions when inhaled. While most people aren't bothered by it, those with sensitivities can experience significant respiratory symptoms, chronic inflammation, and reduced quality of life, making identification and avoidance important for managing health.

What does a high IgG level to Rhizopus nigricans mean?

Elevated IgG antibodies to Rhizopus nigricans suggest your immune system has been exposed to this mold and has developed a delayed-type immune response. This can indicate chronic or repeated exposure causing ongoing inflammation that may contribute to persistent symptoms like congestion, coughing, or fatigue. High levels suggest you should focus on identifying and eliminating sources of this mold in your environment to reduce your symptoms and immune system burden.
