What's this test for?

This test is ideal if you're experiencing sneezing, a stuffy or runny nose, itchy eyes, or coughing during ragweed season. It checks whether your immune system reacts to western ragweed pollen, a common trigger for seasonal allergy symptoms. It's a helpful first step if you suspect pollen is behind your seasonal discomfort.

What happens after I get my results?

Your results will show up in your account with the normal range explained so you can see exactly where you stand. If your result comes back elevated, simple next steps include limiting outdoor time when ragweed pollen counts are high, keeping windows closed, and using air filters at home. You can download the full lab report from your account anytime, and if you retest in a future season, the trends feature lets you track changes over time. If your symptoms feel severe or you have trouble breathing, seek medical care right away.

Who should consider this test?

Anyone who gets sneezing, itchy eyes, or nasal congestion mainly in late summer or fall — ragweed season — should consider this test. It's also useful if you've never pinpointed what triggers your seasonal symptoms and want a clearer answer. People with a family history of pollen allergies may also find it worthwhile.

What symptoms indicate I may need this test?
Common signs include a runny or stuffy nose, sneezing, itchy or watery eyes, scratchy throat, and coughing that shows up around the same time each year. Some people also notice worse symptoms on windy days or after spending time outdoors. If these symptoms repeat seasonally rather than year-round, ragweed could be a factor worth checking.
How can I naturally support seasonal allergy symptoms?
Rinsing your sinuses with a saline rinse, showering after being outdoors, and keeping windows shut during high-pollen days can all reduce exposure. Some people find relief with local honey, quercetin, or vitamin C, though results vary person to person. Keeping indoor air clean with a HEPA filter and washing bedding often can also help lower your overall pollen load.
When will I get my results?
Results are typically ready within about 7 days of your lab visit. Once processed, they're uploaded directly to your secure online account so you can view them as soon as they're available.
What is IgE and why does it matter?
IgE is a type of antibody your immune system makes when it reacts to something it sees as a threat, like pollen. When you're sensitized to an allergen, your body produces specific IgE against it, which can trigger symptoms like sneezing or itching upon exposure. Measuring ragweed-specific IgE helps show whether your immune system recognizes and reacts to this particular pollen.
What does a high IgE result mean?
A high result means your immune system is sensitized to western ragweed pollen and may react when you're exposed to it. It doesn't automatically mean you'll have noticeable symptoms — some sensitized people stay symptom-free. If you do have seasonal symptoms alongside a high result, avoiding exposure and using allergy-friendly habits can help.
What causes a high ragweed IgE result?
A high result happens when your immune system has been exposed to ragweed pollen and developed a sensitized response over time. This is more common in people with a personal or family history of seasonal allergies, asthma, or eczema. Repeated exposure to pollen, especially growing up in ragweed-heavy regions, can also increase the likelihood of sensitization.
How often should I retest?
Most people don't need to retest often unless their symptoms change significantly or they move to a new region with different pollen exposure. If you're trying treatments or lifestyle changes to manage symptoms, retesting once a year during allergy season can help you track whether your sensitization is changing over time.

What this means

This result shows a positive sensitization to western ragweed pollen, meaning your immune system recognizes it as a trigger. This doesn't guarantee you'll have symptoms, but it does raise the chance that ragweed contributes to seasonal allergy issues you may notice in late summer or fall.

* Regular blood test results (e.g., CBC) typically start arriving the next business day after sample collection. More advanced tests may take longer due to complexity.
