What's this test for?

This test is ideal if you're experiencing sneezing, itchy eyes, a runny nose, coughing, or breathing trouble that seems to flare up around damp or moldy environments. Cladosporium herbarum is one of the most common outdoor and indoor molds, and this test checks whether your immune system reacts to it. It's especially useful if your symptoms get worse in humid weather, in basements, or around decaying leaves and plants.

What happens after I get my results?

Your results show up in your account with your IgE level clearly explained alongside the normal reference range, so you can see exactly where you fall. If your level comes back elevated, practical next steps include reducing mold exposure at home, using a dehumidifier, and cleaning damp areas regularly, while a very high or unclear result may call for seeking further evaluation. You can download a standard lab report straight from your account any time, and if you retest down the road, the trends feature lets you track how your IgE response changes over time.

Who should consider this test?

Anyone with ongoing respiratory or skin symptoms that flare up in damp, humid, or moldy environments should consider this test. It's also useful for people who live in older or water-damaged buildings, work outdoors during fall when mold spore counts rise, or have a family history of mold allergies. If antihistamines or other medications you're taking make skin allergy testing unreliable, this blood-based option is a good alternative.

What symptoms indicate I may need this test?

Common signs include sneezing, nasal congestion, itchy or watery eyes, throat irritation, coughing, wheezing, or skin rashes that worsen in humid conditions or around mold-prone spaces like basements, bathrooms, or piles of leaves. Some people also notice their symptoms are seasonal, picking up in warm, wet months when mold spores are highest. If over-the-counter allergy medicine only partly helps, it's worth checking whether mold is the trigger.

When will I get my results?

Results are typically ready within about 7 days of your sample being processed at the lab. You'll get a notification once they're posted to your account, where you can view the detailed report at your convenience. No need to call or wait on hold — everything is accessible online as soon as it's ready.

How can I naturally support my body against mold allergy symptoms?

Simple steps like running a dehumidifier to keep indoor humidity below 50%, fixing leaks promptly, and improving ventilation in bathrooms and kitchens can meaningfully cut your mold exposure. Regularly cleaning surfaces prone to mildew, using HEPA air filters, and avoiding raking leaves or working in compost piles without a mask also help. Staying hydrated and supporting your immune system with a balanced diet rich in fruits and vegetables may ease overall sensitivity, though these habits work best alongside avoiding known triggers.

What does a high IgE result mean?

A high IgE level to Cladosporium herbarum means your immune system has built up a sensitivity to this mold and is likely to react when you're exposed to it. This can show up as allergy symptoms like congestion, itchy eyes, or coughing whenever mold spore counts are high nearby. The higher the number, the stronger the reaction tends to be, but the exact level doesn't always predict how severe your symptoms will feel.

What causes a high Cladosporium IgE result?

Repeated or heavy exposure to mold spores, especially in damp basements, poorly ventilated bathrooms, or outdoor environments with decaying plant matter, is the main driver of a high result. Genetics also play a role, since people with a family history of allergies or asthma tend to develop stronger IgE responses to common allergens. Living or working in older buildings with hidden water damage is another frequent contributor.

How often should I retest?

If you're actively working on reducing mold exposure at home, retesting after 3 to 6 months can help you see whether your IgE levels are trending down. Otherwise, annual retesting is reasonable if you continue to have symptoms or move to a new environment. Tracking results over time through the trends feature makes it easy to spot patterns tied to seasons or home changes.

What should I do if my results are abnormal?

Start by reducing your exposure to mold sources at home and outdoors, such as fixing leaks, running a dehumidifier, and avoiding damp areas during high pollen or mold seasons. Over-the-counter antihistamines can help manage day-to-day symptoms while you make these changes. If symptoms are severe, worsening, or include difficulty breathing, seek medical care right away rather than waiting.
