What's this test for?
This test is ideal if you're experiencing digestive issues like bloating, stomach pain, nausea, or diarrhea after consuming dairy products. It helps identify whether you have an IgE-mediated allergy to lactase, which is different from lactose intolerance and can cause more severe allergic reactions. Many people use this test when they suspect dairy is causing their symptoms but want concrete answers to guide their diet.
How should I prepare for this test?
No special preparation is typically needed for this allergy test. You can continue eating your normal diet, including dairy products, before testing. In fact, it's best not to eliminate suspected allergens before the test, as this provides the most accurate picture of your body's immune response. If you're taking antihistamines or other allergy medications, check with your healthcare provider about whether to continue them.
What's included in this test?
This test measures Allergen Specific IgE Lactase, which evaluates your immune system's reaction to lactase-containing dairy products. It identifies whether your body produces IgE antibodies in response to dairy exposure, which can trigger allergic reactions ranging from mild digestive upset to more serious symptoms. This specific measurement helps distinguish a true dairy allergy from lactose intolerance or other digestive conditions.
What happens after I get my results?
You'll receive detailed doctor notes in simple language explaining what your IgE levels mean for your food sensitivities and digestive health. These notes include personalized recommendations like dietary modifications, foods to avoid or reintroduce, and whether you should consider consulting an allergist. You'll also get the standard lab report and can track your allergy markers over time using our trends feature to see if your sensitivity changes.
When will I get my results?
Most allergy test results are available within 3-5 business days after your blood sample reaches the lab. You'll receive an email notification when your results are ready to view in your secure online account. If you have urgent symptoms or concerns, your healthcare provider may recommend additional testing or evaluation while waiting for results.
Who should consider getting this test?
This test is ideal for anyone experiencing digestive problems, skin reactions, or respiratory symptoms after eating dairy products. It's especially useful if you've already tried eliminating dairy and want to confirm whether you have a true allergy, or if you're experiencing inconsistent reactions to different dairy foods. People with a family history of food allergies or those who have other allergies may also benefit from testing.
What symptoms indicate I may need this test?
Common symptoms include digestive upset like bloating, cramping, nausea, or diarrhea within hours of eating dairy. You might also experience skin reactions like hives or itching, respiratory symptoms like wheezing or nasal congestion, or even mouth tingling after consuming dairy products. If you notice a pattern of these symptoms consistently occurring after eating cheese, milk, yogurt, or other dairy foods, this test can help identify the cause.
What's the difference between a dairy allergy and lactose intolerance?
A dairy allergy involves your immune system producing IgE antibodies against dairy proteins, which can cause immediate allergic reactions affecting multiple body systems. Lactose intolerance is a digestive issue where your body lacks the enzyme to break down milk sugar, causing primarily digestive symptoms. This test specifically checks for the allergic response, not lactose intolerance, which requires different testing.
What does a positive result mean?
A positive result means your body produces IgE antibodies in response to lactase-containing dairy products, confirming a true allergic reaction. The severity is often classified by the level of IgE detected, ranging from low to very high sensitivity. This means you'll need to carefully avoid dairy products or work with an allergist to determine which dairy foods you can safely consume and which you should eliminate.
What should I do if my results show a dairy allergy?
Start by eliminating or significantly reducing dairy products from your diet and carefully reading food labels for hidden dairy ingredients. Focus on dairy alternatives like almond milk, oat milk, or coconut-based products to ensure adequate calcium and vitamin D intake. Keep a food diary to track symptoms and reactions, and consider consulting with an allergist or dietitian to develop a safe, nutritionally balanced eating plan that avoids your trigger foods.

What this means
Your test came back negative, meaning no IgE antibodies to lactase were detected in your blood. This suggests your digestive symptoms after dairy consumption are likely not due to a true dairy allergy, and may be caused by lactose intolerance or another digestive issue instead.
Recommended actions
Consider testing for lactose intolerance if dairy still causes symptoms
Keep a food diary to identify other potential trigger foods
Gradually reintroduce dairy products while monitoring symptoms
Consult with a gastroenterologist if digestive issues persist
* Regular blood test results (e.g., CBC) typically start arriving the next business day after sample collection. More complex tests, such as hormone panels, may take up to 10–15 business days due to their complexity.
