You’re not alone if you’ve ever wondered whether that belly pain after a meal might be due to a hidden food allergy. You may have even considered those convenient food allergy panels you can order online or pick up from a pharmacy for quick answers. But before you use those, it’s important to understand their accuracy—or lack thereof. Here’s why these panels often miss the mark and why seeing a board-certified allergist is your best bet.
What Are Food Allergy Panels?
What are food allergy panels? These tests, often marketed as comprehensive allergy or food sensitivity solutions, claim to give you a detailed breakdown of what foods your body might be reacting to by measuring IgG levels. Essentially, these panels promise to reveal all the hidden food culprits wreaking havoc on your body, from digestive discomfort to fatigue.
Unfortunately, it’s not that simple. While the appeal of getting fast results from a single test is tempting, the reality is that they don’t actually provide the accurate answers they advertise. That’s because they’re designed to measure IgG levels, which aren’t reliable indicators of food allergies. In fact, they can even mislead you into cutting out foods that aren’t actually the issue at all.
IgG Testing: Why It’s Not the Answer
IgG, or Immunoglobulin G, is an antibody your body produces when it’s exposed to various substances, including food. But higher IgG levels don’t necessarily mean you’re allergic to a food. In reality, they could be a sign that your body has developed a tolerance to that food, not a rejection of it. So, when food allergy panels measure your IgG response, they’re not giving an accurate picture of what foods are genuinely causing problems.
Several major health organizations, including the American Academy of Allergy, Asthma & Immunology, advise against using IgG testing for this purpose. Without reliable science to support it, these tests can lead you down the wrong path—cutting out foods you enjoy and need and leaving you still feeling unwell.
What is the Difference Between a Food Allergy and a Food Sensitivity?
Food allergies and food sensitivities or intolerances are not the same thing. With a true food allergy, your immune system has mounted an immune response to the offending food, which can lead to serious and sometimes life-threatening reactions like anaphylaxis. This is why it’s so important to get an accurate diagnosis.
On the other hand, food sensitivities or intolerances are more about your body having trouble processing certain foods. They can still cause unpleasant symptoms like bloating, fatigue, or headaches, but they don’t involve the immune system like a true allergy does. Food allergy panels often fail to distinguish between these, leading to confusion and misdiagnosis.
Why You Should See an Allergist
An allergist is a trained specialist who can give you the right tests (like skin prick or blood tests) scientifically proven to diagnose food allergies accurately. They’ll also help distinguish between an allergy, a sensitivity, or something else, like a digestive issue. Seeing a professional doesn’t just give you peace of mind; it can save you from unnecessary dietary restrictions. Plus, an allergist can provide tailored advice to manage your symptoms effectively without the guesswork.
