What's this test for?

This test is ideal if you're experiencing digestive discomfort, bloating, skin reactions, or unexplained fatigue that seems to show up after eating certain grains or being around grass pollen. It measures your immune system's IgG4 response to meadow fescue, a common grass, to help you figure out if it could be contributing to your symptoms. It's a helpful starting point if you suspect a food or environmental sensitivity but aren't sure what's triggering it.

What happens after I get my results?

Your results will show up in your account with your IgG4 level clearly marked against the normal range, along with an explanation of what that range means. If your level comes back elevated, a simple next step is to try reducing your exposure to meadow fescue and related grass products for a few weeks and see if your symptoms improve. You can download a standard lab report from your account at any time, and the trends feature lets you track this marker over time if you decide to retest later.

What is meadow fescue and why does it matter?

Meadow fescue is a common type of grass found in lawns, pastures, and some grain crops. For some people, repeated exposure to it through food or environmental contact can trigger an immune response that shows up as digestive issues, skin irritation, or respiratory symptoms. Understanding your sensitivity to it can help you make more informed choices about diet and environmental exposure.

How should I naturally support a grass sensitivity?

If you find you're sensitive to meadow fescue, try keeping a food and symptom journal to spot patterns and avoid obvious triggers. Simple steps like rinsing off after being in grassy areas, washing produce well, and choosing whole, unprocessed grains can reduce your exposure. Some people also find relief by supporting gut health with probiotic-rich foods, since a healthy gut lining may reduce sensitivity reactions over time.

When will I get my results?

Results are typically ready within about 7 days of your sample being processed at the lab. You'll get a notification as soon as your report is available in your online account, so there's no need to call or check in manually.

Who should consider this test?

This test is a good fit for anyone who notices recurring digestive, skin, or respiratory symptoms after eating grain products or spending time outdoors in grassy areas. It's also useful if you've already ruled out other common causes and want to explore whether a grass-related sensitivity could be playing a role. People with a family history of allergies or sensitivities may also find this test worth exploring.

What symptoms indicate I may need this test?

Common signs include bloating, stomach cramps, diarrhea, skin rashes or hives, itchy eyes, or a stuffy nose that seems to flare up after eating grains or being outside during grass pollen season. Fatigue or headaches that don't have an obvious cause can sometimes be linked too. If these symptoms keep coming back and you can't pinpoint why, this test can help narrow things down.

What does a high IgG4 result mean?

A high result means your immune system is producing more antibodies in response to meadow fescue than is typical, which may suggest your body reacts to it more than average. This doesn't automatically mean you're allergic, but it can be a useful clue if you're trying to connect symptoms to specific exposures. Many people with elevated results find that reducing contact with the trigger for a few weeks helps them see if symptoms ease up.

How often should I retest?

If you make changes based on your first result, like reducing exposure to meadow fescue, retesting after 8-12 weeks can help you see if your levels have changed. If your first result was normal but symptoms persist, you might consider retesting after a few months or exploring other potential triggers. Tracking results over time in your account makes it easy to see these changes clearly.

What should I do if my results are abnormal?

Start by looking at where meadow fescue shows up in your diet and environment, such as certain grains, grasses, or outdoor activities, and try reducing exposure for a few weeks. Keep track of your symptoms during this time to see if there's improvement. If symptoms are severe or don't improve, or if you experience trouble breathing or swelling, seek medical care right away.
