What's this test for?

This test is ideal if you're experiencing sneezing, itchy eyes, a stuffy nose, coughing, or skin irritation that seems to flare up at certain times of year or in certain environments. Helminthosporium sativum (also called Drechslera) is a common outdoor mold, and this test checks whether your immune system reacts to it. It's especially useful if you notice your symptoms get worse during humid weather, after mowing the lawn, or in damp indoor spaces.

What's included in this test?

This is a single-marker test that measures IgE antibodies specific to Helminthosporium sativum/Drechslera mold. IgE is the antibody your immune system produces when it identifies something as a threat, so a higher level suggests your body is sensitized to this particular mold. Testing one allergen at a time lets you pinpoint whether this specific mold is behind your symptoms.

What happens after I get my results?

Your results will show up in your account with a clear explanation of what a normal versus elevated IgE range means for this mold allergen. If your level comes back elevated, simple next steps include reducing your exposure to damp or moldy environments, using air filters, and considering an over-the-counter antihistamine to manage symptoms. If your reaction is severe, such as trouble breathing, seek medical care right away. You can download the standard lab report from your account any time and track your results over time using the trends feature if you retest later.

How can I naturally support my immune response to mold allergies?

Reducing exposure is the most effective natural step: keep indoor humidity below 50%, use a dehumidifier in damp areas, and clean visible mold with vinegar or a mild bleach solution. Eating anti-inflammatory foods like leafy greens, fatty fish, and turmeric may help calm an overactive immune response. Nasal saline rinses and staying well hydrated can also help clear allergens from your airways naturally.

When will I get my results?

Results are typically ready within about 7 days of your lab visit. Once processed, they'll be posted directly to your online account, and you'll be notified when they're ready to view. No need to call or wait for a mailed report.

Who should consider this test?

Anyone with recurring allergy-like symptoms — especially seasonal sneezing, congestion, itchy or watery eyes, or skin rashes — that seem tied to outdoor air quality or damp environments should consider this test. It's also useful for people who've had unexplained respiratory symptoms and want to rule out mold sensitivity as a cause. If you work or spend time in agricultural, farming, or humid environments where this mold is common, testing can help clarify your triggers.

What symptoms indicate I may need this test?

Common symptoms include a runny or stuffy nose, sneezing fits, itchy or watery eyes, coughing, wheezing, or skin hives that flare up during humid or damp conditions. Some people also notice worsening asthma symptoms or sinus pressure. If these symptoms show a pattern tied to weather, outdoor exposure, or damp indoor spaces, this test can help confirm a mold connection.

What does a high IgE result mean?

A high IgE level for this mold means your immune system has identified Helminthosporium sativum as a threat and is producing antibodies against it, which is what triggers allergy symptoms like sneezing or itchy eyes. The higher the level, the more sensitized your body tends to be, though symptom severity can still vary person to person. Reducing exposure and managing symptoms with antihistamines or nasal sprays are common first steps.

What causes a high IgE reaction to this mold?

High IgE reactions happen when your immune system has been repeatedly exposed to mold spores and has learned to treat them as harmful invaders, even though they're not dangerous to most people. Living or working in damp, poorly ventilated spaces, spending time around decaying plant matter, or seasonal spore counts can all increase exposure and reaction risk. Genetics also play a role — allergies often run in families.

How often should I retest?

If you're actively working to reduce mold exposure or trying a new treatment approach, retesting after 3-6 months can help you see if your IgE levels are trending down. Otherwise, annual testing is reasonable if you continue to have seasonal or environment-related symptoms. Tracking results over time in your account can help you see whether your management steps are working.
