What's this test for?

This test is ideal if you're experiencing sneezing, itchy eyes, skin reactions, or unexplained congestion that seems to flare up at certain times. It checks whether your immune system reacts to hickory (white) tree pollen, which is a common trigger for seasonal allergy symptoms. Knowing whether hickory is a trigger can help you figure out what's behind your symptoms and when they're most likely to happen.

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 IgG4 level means for hickory exposure. If your level is elevated, simple next steps include tracking your symptoms during hickory pollen season, reducing outdoor exposure on high pollen days, and considering an air filter at home. You can download a standard lab report from your account at any time, and if you retest later, the trends feature lets you see how your levels change over time.

What symptoms indicate I may need this test?

Common signs include sneezing, a runny or stuffy nose, itchy or watery eyes, skin rashes, or mild breathing trouble that seems to show up during certain seasons or after being outdoors near trees. If these symptoms come and go with the seasons rather than being constant, an environmental allergy trigger like hickory pollen could be worth checking. Tracking when your symptoms flare up can help you connect them to pollen exposure.

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

Simple habits like rinsing your sinuses with saline, showering after being outside, and keeping windows closed during high pollen days can reduce your exposure. Eating a diet rich in fruits, vegetables, and omega-3s may help support a balanced immune response. Staying hydrated and getting enough sleep also help your body manage inflammation from allergy triggers.

When will I get my results?

Results are typically ready within about 7 days of your lab visit. You'll get a notification once they're posted to your account, where you can view and download the full report.

Who should consider this test?

Anyone who notices recurring allergy-like symptoms during certain seasons, especially in areas with hickory trees, may want to consider this test. It's also useful if you've already tried general allergy remedies without knowing your specific trigger. People who want to plan ahead for pollen season, like adjusting outdoor activities or medication timing, can benefit too.

What is IgG4 and why does it matter?

IgG4 is a type of antibody your immune system makes in response to repeated exposure to a substance, like tree pollen. Measuring hickory-specific IgG4 can help show whether your body has developed a notable immune response to this particular allergen. This information can be one piece of the puzzle when figuring out what's triggering your symptoms.

What does a high IgG4 result mean?

A higher level suggests your immune system has had significant exposure to hickory pollen and has built up a response to it. This doesn't always mean you'll have symptoms, but combined with your symptom pattern, it can point to hickory as a likely trigger. If your result is high, avoiding exposure on high-pollen days and monitoring your symptoms can help you manage things day to day.

How often should I retest?

If you're using this test to track a known sensitivity, retesting once a year or after a pollen season can help you see if your levels are changing. If you're newly investigating symptoms, you may not need to retest unless your symptoms change significantly or you want to check your levels after making lifestyle changes.

What should I do if my results are abnormal?

If your hickory IgG4 level comes back elevated, start by tracking when your symptoms occur and comparing that to local pollen forecasts. Small changes like limiting outdoor time during peak pollen hours, using an air purifier, and rinsing off after being outside can reduce your exposure. If symptoms are severe, such as difficulty breathing, seek medical care right away.
