What's this test for?

This test is ideal if you're experiencing mysterious symptoms after eating shellfish like hives, itching, swelling, stomach issues, or breathing difficulties. It helps identify whether you have an allergic reaction to common shellfish including clam, crab, lobster, or shrimp by measuring your body's IgE antibody response. Many people use this test when they suspect certain seafood is causing their symptoms but want concrete answers about which specific shellfish to avoid.

What happens after I get my results?

You'll receive detailed doctor notes in simple language explaining which shellfish triggered an IgE response and what your levels mean for your symptoms. These notes include personalized recommendations on which seafood to avoid, how to read restaurant menus safely, and when you might need an EpiPen or allergy specialist consultation. You'll also get the standard lab report and can track your IgE levels over time using our trends feature to monitor changes or confirm if allergen avoidance is working.

What's included in this test?

This panel measures IgE antibody levels for Clam (f207), Crab (f23), Lobster (f80), and Shrimp (f24). IgE antibodies are produced by your immune system when it mistakenly identifies certain proteins as threats, triggering allergic reactions ranging from mild itching to severe anaphylaxis. By testing each shellfish separately, this panel helps pinpoint exactly which types you may be sensitive to, so you can make informed decisions about what's safe to eat.

How should I prepare for this test?

No special preparation is needed for this allergy blood test. You don't need to fast, and you can take your regular medications including antihistamines, which is an advantage over skin testing. Unlike allergy skin tests that require you to stop antihistamines beforehand, this blood test measures IgE antibodies directly and isn't affected by allergy medications you're currently taking.

Who should consider getting this test?

This test is important for anyone experiencing allergic symptoms after eating shellfish, especially if reactions are getting worse over time. It's particularly useful for people with widespread skin conditions like eczema where skin testing isn't practical, children who may be uncooperative for skin prick tests, and anyone with a history of severe allergic reactions where skin testing could be risky. It's also helpful if you've been taking antihistamines and can't stop them for traditional skin testing.

What symptoms indicate I may need this test?

Common symptoms that suggest a shellfish allergy include hives, itching or tingling in your mouth, swelling of your lips or face, stomach cramps, nausea, or diarrhea after eating seafood. More serious symptoms can include wheezing, difficulty breathing, dizziness, or a drop in blood pressure. If you've noticed these reactions happening repeatedly after shellfish meals, this test can help confirm whether an IgE-mediated allergy is the cause.

What does a positive result mean?

A positive result means your blood contains IgE antibodies specific to one or more of the shellfish tested, indicating you're sensitized to that particular shellfish. However, it's important to know that being sensitized doesn't always mean you'll have symptoms when eating it. Your doctor will interpret your results alongside your actual symptoms and medical history to determine whether you have a true food allergy that requires avoiding those shellfish completely.

Can I outgrow a shellfish allergy?

Unlike some childhood food allergies like milk or egg, shellfish allergies typically develop in adulthood and are usually lifelong. Studies show that only about 5-10% of people with shellfish allergies may eventually outgrow them, and this is much less common than outgrowing other food allergies. If you've been diagnosed with a shellfish allergy, it's important to continue avoiding those foods and carry emergency medication unless your allergist confirms through testing and supervised challenges that you've outgrown it.

What should I do if my test shows high IgE levels?

If your test shows elevated IgE levels to certain shellfish, the most important step is to strictly avoid those specific shellfish in your diet and carefully read food labels and restaurant menus. Work with an allergist to develop an emergency action plan, and they may prescribe an epinephrine auto-injector if you're at risk for severe reactions. Be aware that shellfish proteins can contaminate other foods during cooking, so inform restaurant staff about your allergy and consider consulting a dietitian for guidance on safe food choices and hidden sources.

How often should I retest for shellfish allergies?

Retesting is typically recommended every 1-2 years if you're hoping to see if you've outgrown the allergy, though this is rare with shellfish. Your allergist may also suggest retesting if your symptoms change significantly or if you accidentally ate shellfish without a reaction. For most adults with confirmed shellfish allergies, regular retesting isn't necessary since these allergies tend to be permanent, and management focuses on strict avoidance rather than monitoring for resolution.
