What's this test for?

This test is ideal if you're experiencing ongoing nasal congestion, sneezing, itchy or runny nose, or postnasal drip that won't go away. It helps figure out whether allergies (allergic rhinitis) are the cause of your symptoms, rather than a cold, sinus infection, or other issue. It's especially useful if over-the-counter allergy medicine hasn't given you clear answers about what's triggering your symptoms.

What's included in this test?

This test measures the number of eosinophils, a type of white blood cell, in a sample collected from your nasal passage. Eosinophils rise when your immune system is reacting to an allergen, so counting them helps distinguish an allergic cause of nasal symptoms from a non-allergic one like infection or irritants.

What happens after I get my results?

Your results will show up in your account with a clear explanation of what counts as a normal versus elevated eosinophil level. If your levels are high, simple next steps include identifying and reducing exposure to common triggers like dust, pollen, or pet dander, and trying an antihistamine to see if symptoms improve. If symptoms are severe or you have trouble breathing, seek medical care right away. You can download the full lab report from your account anytime, and use the trends feature to track your results if you retest in the future.

How can I naturally support healthy sinus and allergy response?

Reducing exposure to common allergy triggers like dust mites, pollen, mold, and pet dander can make a real difference. Using a saline nasal rinse, running an air purifier, and keeping windows closed during high pollen days are simple ways to calm nasal irritation. Staying hydrated and getting enough sleep also help your immune system respond more calmly to everyday irritants.

When will I get my results?

Results are typically ready within about 7 days of your sample being processed at the lab. Once ready, they'll be posted directly to your online account so you can view and download them at your convenience.

Who should consider this test?

Anyone with recurring nasal symptoms like congestion, sneezing, or itchy nose that seem tied to seasons, pets, dust, or other environmental triggers should consider this test. It's also helpful for people who've tried allergy medications without knowing for sure if allergies are actually the cause. Parents trying to understand a child's chronic sniffles or stuffy nose may also find this useful.

What symptoms indicate I may need this test?

Common signs include a stuffy or runny nose that lasts for weeks, frequent sneezing, itchy nose or eyes, and postnasal drip. If these symptoms show a pattern, like getting worse around pets, dust, or specific seasons, that's a strong hint allergies could be involved. Nasal symptoms that don't respond to typical cold remedies are another clue worth checking out.

What does a high eosinophil count mean?

A higher-than-normal eosinophil count in your nasal sample usually means your immune system is reacting to an allergen, pointing toward allergic rhinitis as the cause of your symptoms. This doesn't tell you exactly what you're allergic to, but it confirms allergies are likely playing a role. From here, tracking your triggers and trying allergy-focused strategies like antihistamines or environmental changes is a reasonable next step.

What causes a high eosinophil count in nasal samples?

The most common cause is an allergic reaction to things like pollen, dust mites, mold, or pet dander. Chronic sinus inflammation and certain other immune-related nasal conditions can also raise eosinophil levels. Identifying and reducing contact with your specific triggers is usually the most effective way to bring symptoms under control.

How often should I retest?

If you're managing symptoms with lifestyle changes or medication, retesting once every few months during allergy season can help you see if your approach is working. If your symptoms change significantly or new triggers appear, retesting sooner can offer useful insight. Using the trends feature lets you compare results over time to see patterns.
