What's this test for?

This test is ideal if you're experiencing hives, digestive upset, bloating, or skin reactions after eating foods or drinks made with brewer's yeast, like beer, bread, or wine. It's also useful if you've noticed unexplained itching, stomach cramps, or breathing issues that seem tied to something you ate or drank. Identifying a yeast allergy can help you figure out what's triggering your symptoms so you can avoid it going forward.

What happens after I get my results?

Your results will show up in your account, with an explanation of what a normal versus elevated IgE level means for brewer's yeast sensitivity. If your result comes back elevated, a practical next step is eliminating brewer's yeast-containing foods and drinks for a few weeks to see if your symptoms improve. You can download a standard lab report from your account at any time, and if you retest later, the trends feature lets you track changes in your IgE levels over time.

Who should consider this test?

Anyone who notices repeated symptoms like hives, bloating, or itching after eating bread, beer, wine, or other fermented foods should consider this test. It's also helpful for people with a family history of food allergies who want to pinpoint specific triggers. If you've already cut out other common allergens without relief, checking brewer's yeast can help narrow things down.

What symptoms indicate I may need this test?

Common signs include hives or skin rashes, itching around the mouth or throat, bloating, stomach cramps, or nausea after eating yeast-containing foods. Some people also notice mild breathing changes like a stuffy nose or throat tightness. If these symptoms show up consistently after specific meals or drinks, it's worth checking whether brewer's yeast is the cause.

How can I naturally support a food sensitivity?

Keeping a food and symptom diary can help you spot patterns before or after testing. Eating a balanced diet rich in whole foods, staying hydrated, and reducing processed or fermented foods can ease digestive stress on your body. Probiotic-rich foods like plain yogurt may also help support gut balance, though you should stop these temporarily if you're trying to isolate a specific trigger.

When will I get my results?

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

What does high brewer's yeast IgE mean?

A high IgE result means your immune system has developed a sensitivity to brewer's yeast proteins, which can trigger symptoms like hives, itching, or digestive upset when you're exposed to it. This doesn't necessarily mean a severe allergy, but it does suggest your body reacts to it. Avoiding foods and drinks made with brewer's yeast is a reasonable first step to see if your symptoms ease up.

What causes a brewer's yeast allergy?

An allergy develops when your immune system mistakenly identifies proteins in brewer's yeast as harmful and produces antibodies against them. This can happen after repeated exposure through foods like beer, bread, wine, or nutritional yeast supplements. Genetics and having other allergies can also make you more likely to develop sensitivities like this one.

How often should I retest?

If you've made dietary changes to avoid brewer's yeast, retesting in 3-6 months can help confirm whether your IgE levels have gone down. If your symptoms resolve and stay away, you may not need to retest unless new symptoms appear. For ongoing or worsening symptoms, more frequent monitoring may be helpful.

What should I do if my results are abnormal?

Start by avoiding foods and beverages that contain brewer's yeast, such as beer, wine, and certain breads, to see if your symptoms improve. Reading ingredient labels carefully can help you spot hidden sources. If you ever experience severe symptoms like difficulty breathing or swelling, seek medical care right away, as this could signal a more serious reaction.
