What's this test for?

This test is ideal if you're experiencing repeated respiratory symptoms, skin reactions, or unexplained congestion and you suspect a mold-related allergy may be involved. It measures your immune system's IgG antibody response to Penicillium chrysogenum/notatum, a common environmental mold. It's often used to help understand possible past exposure to this specific mold when other explanations haven't panned out.

What happens after I get my results?

Your results will show up in your account with the normal range clearly explained next to your value. If your level is elevated, simple next steps include reducing mold exposure at home or work, improving ventilation, and considering a retest in a few months to see if levels change. A standard lab report is available to download from your account any time, and you can track this result over time using the trends feature to see how it shifts.

Who should consider this test?

This test is generally intended for use when guided by someone familiar with the limits of allergen-specific IgG testing, since results don't always correlate with symptoms or disease. It may be considered if you've had ongoing, unexplained allergy-like symptoms and want more information about possible mold exposure. It's best used alongside other information about your environment and health history.

How can I naturally support my body against mold exposure?

Simple steps include improving indoor air quality with good ventilation and a HEPA air filter, fixing any damp or leaky areas in your home, and regularly cleaning areas prone to moisture like bathrooms and basements. Eating a diet rich in antioxidants can support your immune system generally. Reducing clutter and using a dehumidifier can also help lower mold levels in your living space.

When will I get my results?

Results are typically ready within about 7 days of your lab visit. Once ready, they'll be posted directly to your online account where you can view and download them. You'll be able to see your specific value alongside the reference range so you can understand where you stand.

What symptoms indicate I may need this test?

Common signs include ongoing sneezing, nasal congestion, itchy or watery eyes, coughing, or skin reactions that seem to worsen in damp or moldy environments. If you notice symptoms flare up in basements, older buildings, or humid weather, mold sensitivity could be a factor. Persistent, unexplained respiratory irritation is another reason people consider this type of testing.

What is Penicillium mold and why does it matter?

Penicillium chrysogenum/notatum is a very common mold found indoors and outdoors, especially in damp areas, on old food, or in poorly ventilated spaces. Some people's immune systems react to it, producing antibodies like IgG in response to exposure. Understanding your antibody levels can offer a piece of the puzzle when investigating unexplained allergy-type symptoms.

What does a high IgG result mean?

A higher IgG level generally suggests your immune system has been exposed to and responded to this specific mold at some point. It doesn't necessarily mean you're currently having an allergic reaction, since IgG reflects exposure history rather than an active allergy in most cases. It's one data point that's most useful when considered alongside your symptoms and living or work environment.

What causes elevated Penicillium IgG levels?

Elevated levels are usually linked to exposure to damp or moldy environments, such as older buildings, basements, poorly ventilated bathrooms, or areas with water damage. Frequent contact with mold-prone foods or agricultural settings can also contribute. Reducing ongoing exposure is the most direct way to address rising levels over time.

How often should I retest?

If you're making changes to reduce mold exposure, retesting every few months can help you track whether your levels are trending down. Otherwise, retesting isn't usually needed unless your symptoms change or you move to a new environment with different mold exposure risks. Use the trends feature in your account to compare results side by side.
