What's this test for?

This test is ideal if you're experiencing bloating, stomach pain, skin issues, or other unexplained symptoms after consuming dairy products. It measures your immune system's IgG antibody response to cow's milk, which can help you understand if milk might be contributing to how you feel. Many people use this test to explore possible food sensitivities beyond a classic milk allergy.

What's included in this test?

This test includes a single, focused measurement of IgG antibodies specific to cow's milk proteins. This matters because IgG antibody levels can reflect how your immune system reacts to a food over repeated exposure, which some people find useful for identifying possible dietary triggers behind ongoing digestive or skin complaints.

What happens after I get my results?

Your results will show up in your account with your IgG level clearly explained alongside the normal reference range. If your result is elevated, a practical next step is trying an elimination approach where you remove cow's milk from your diet for a few weeks and track how you feel, then reintroduce it slowly to observe any changes. 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. If you notice severe symptoms like difficulty breathing or swelling, seek medical care right away, as that suggests a different type of reaction.

How can I naturally support digestive comfort?

Simple changes like trying lactose-free or plant-based milk alternatives can ease discomfort if dairy is a trigger for you. Eating smaller, more frequent meals and adding probiotic-rich foods like yogurt (if tolerated) or fermented vegetables can support gut health. Staying hydrated and reducing processed foods alongside any dietary changes may also help calm digestive symptoms 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 receive a notification once your results are available to view securely in your account. This timeframe allows the lab to accurately measure the IgG antibody response to cow's milk.

Who should consider this test?

This test is a good fit for anyone who notices recurring digestive discomfort, bloating, headaches, or skin issues after eating dairy products. It's also useful for people who suspect a food sensitivity but haven't been able to pinpoint the cause on their own. Parents curious about a child's reaction to dairy-based foods (with appropriate testing) and people managing chronic digestive conditions may also find this test helpful.

What symptoms indicate I may need this test?

Common symptoms include bloating, gas, stomach cramps, diarrhea or constipation after consuming dairy, along with skin issues like eczema or hives. Some people also notice fatigue, headaches, or joint discomfort that seems to follow dairy consumption. If these symptoms show up repeatedly after eating dairy-based foods, this test can help clarify whether cow's milk might be a factor.

What is IgG and why does it matter?

IgG is a type of antibody your immune system makes in response to substances it encounters repeatedly, including certain foods. Elevated IgG to cow's milk suggests your body has built up an immune response to milk proteins, which some people associate with delayed food sensitivity symptoms. Understanding this can help guide dietary choices, though it's different from a true milk allergy, which involves a different antibody (IgE) and faster, more severe reactions.

What does a high IgG result mean?

A high result means your immune system shows a stronger antibody response to cow's milk proteins, which some people link to sensitivity symptoms like bloating or skin flare-ups after eating dairy. It doesn't necessarily mean a dangerous allergy, but many people use this information to try reducing dairy intake and see if symptoms improve. Pairing this with a food diary can help you connect the dots between what you eat and how you feel.

How often should I retest?

If you make dietary changes based on your first result, retesting after 2-3 months can help you see whether your IgG levels have changed. For general monitoring without symptoms, retesting once a year is a reasonable approach. If you reintroduce cow's milk into your diet after avoiding it, retesting can help confirm whether your body's response has shifted.
