What happens after I get my results?

You'll receive detailed doctor notes in simple language explaining whether you have a specific IgE antibody response to xanthan gum and what that means for your health. These notes include personalized recommendations like which foods and products to avoid, how to read ingredient labels effectively, and dietary alternatives to maintain your nutritional needs. You'll also get the standard lab report and can track your antibody levels over time using our trends feature, which is especially helpful if you're implementing dietary changes or monitoring symptom improvement.

When will I get my results?

Most allergy blood tests are processed within 3-5 business days after your sample reaches the laboratory. You'll receive an email notification as soon as your results are ready to view in your secure online account. Complex allergy panels may occasionally take slightly longer, but the typical turnaround is less than a week from your blood draw.

Who should consider getting this test?

This test is ideal for anyone experiencing unexplained allergic reactions, digestive problems like bloating or diarrhea, skin rashes, or respiratory issues after eating processed foods. It's particularly useful for people with gluten-free diets since xanthan gum is commonly used in gluten-free products as a binder. If you've noticed symptoms that occur after eating salad dressings, sauces, ice cream, or other thickened foods, this test can help identify whether xanthan gum is the culprit.

What symptoms indicate I may need this test?

Common symptoms that may indicate a xanthan gum allergy include digestive issues like bloating, gas, stomach cramps, or diarrhea after eating processed foods. You might also experience skin reactions such as hives, itching, or rashes, or respiratory symptoms like wheezing or nasal congestion. Some people report headaches or general feelings of unwellness after consuming products containing xanthan gum, especially in larger quantities.

How can I avoid xanthan gum if I'm allergic?

Carefully read ingredient labels on all packaged foods, as xanthan gum is commonly found in salad dressings, sauces, ice cream, gluten-free baked goods, and dairy products. Choose whole, unprocessed foods whenever possible, and when buying packaged items, look for products that use alternative thickeners like guar gum, arrowroot, or cornstarch. Many natural food stores carry xanthan gum-free alternatives, and you can also make homemade versions of dressings and sauces using simple ingredients.

What is xanthan gum and why does it matter?

Xanthan gum is a food additive created through fermentation that's used as a thickening and stabilizing agent in countless processed foods and personal care products. It helps bind ingredients together, improve texture, and extend shelf life, making it especially popular in gluten-free baking. While generally recognized as safe, some people develop allergic sensitivities that can trigger digestive, respiratory, or skin symptoms, making it important to identify if you're one of them.

What does a positive result mean?

A positive result means your immune system produces IgE antibodies against xanthan gum, indicating a true allergic sensitivity. The level of antibodies detected can help determine the severity of your allergy, with higher levels typically associated with stronger reactions. This result means you should avoid foods and products containing xanthan gum and work with your doctor or dietitian to develop an elimination plan and identify safe alternatives.
