What's this test for?

This test is ideal if you're experiencing ongoing sneezing, stuffy or runny nose, itchy eyes, or trouble breathing that seems to stick around all year, especially indoors. Dust mites are one of the most common triggers of year-round allergy and asthma-like symptoms, and this test helps you find out if they could be the reason. It's a simple way to get answers before trying allergy medications or making changes to your home.

What happens after I get my results?

Your results will show up in your account with a clear explanation of what a positive or negative IgE result means. If your result is positive, practical next steps include reducing dust mite exposure at home, such as washing bedding in hot water and using allergen-proof covers, and watching whether your symptoms improve. You can download the full lab report from your account anytime, and if you retest later you'll be able to track changes over time using the trends feature. If you ever experience severe breathing difficulty, seek medical care right away.

Who should consider this test?

Anyone with ongoing nasal congestion, sneezing, itchy or watery eyes, or asthma symptoms that seem worse indoors or during sleep may want to consider this test. It's especially useful for people whose symptoms don't have an obvious seasonal pattern, since dust mites are present indoors all year. People with a family history of allergies or asthma may also find it helpful to check for dust mite sensitization.

What symptoms indicate I may need this test?
Common signs include a stuffy or runny nose, sneezing fits, itchy or watery eyes, coughing, wheezing, or waking up congested. Symptoms that seem worse in bed, in carpeted rooms, or around upholstered furniture often point toward a dust mite trigger. If over-the-counter allergy remedies only partly help or your symptoms keep coming back, it may be worth checking for a specific cause.
How can I naturally reduce dust mite exposure?
Washing sheets and pillowcases weekly in hot water, using allergen-proof mattress and pillow covers, and keeping indoor humidity below 50% can all help reduce dust mite populations. Vacuuming with a HEPA filter and removing thick carpets or heavy curtains where mites like to collect also makes a difference. Regularly airing out and dusting your bedroom with a damp cloth can further cut down on exposure.
When will I get my results?
Results are typically ready within about 7 days of your lab visit. Once processed, they'll be uploaded securely to your online account, where you'll get a notification that they're ready to view.
What does a high IgE result mean?
A high or positive result means your immune system has produced antibodies that react to dust mite proteins, showing you're sensitized to this allergen. This doesn't automatically mean you have full-blown allergies, but combined with your symptoms it strongly suggests dust mites could be a trigger. Many people find real relief by reducing dust mite exposure in their home once they know this is a factor.
What does a negative result mean?
A negative result means no significant IgE antibodies to dust mites were detected, so they're likely not the cause of your symptoms. If your symptoms continue, it may be worth looking into other common triggers like pet dander, pollen, or mold. Keeping a symptom diary noting when and where symptoms flare up can help you and any future testing narrow down the real cause.
How often should I retest?
Allergy sensitization to dust mites usually doesn't change quickly, so retesting isn't typically needed unless your symptoms change significantly or you want to confirm improvement after making changes to reduce exposure. Many people retest once a year or after major changes to their home environment, like moving or renovating. If your symptoms worsen suddenly, retesting sooner can help confirm what's going on.
What should I do if my results are abnormal?
If your result is positive, start by making practical changes at home, like using allergen-proof bedding covers, washing linens in hot water, and reducing clutter that traps dust. Over-the-counter antihistamines or nasal sprays can help manage symptoms while you make these changes. If symptoms are severe or don't improve with home changes, seeking medical care for further evaluation is a reasonable next step.
