Shellfish Allergy Panel (IgE)
Four common shellfish behind food reactions ranging from hives to anaphylaxis.
Consider this test if:
- Hives, swelling, vomiting, or trouble breathing after eating shellfish
- A past reaction and you want to know which shellfish are involved before eating out
- Sorting out whether a crustacean reaction also extends to mollusks like clam
- Building an allergy history before introducing or reintroducing shellfish
- HSA/FSA eligible
- Results delivered to your dashboard · Reviewed by a real clinician
- Drawn at a CLIA/CAP-accredited lab near you ·
Pre-test considerations
No fasting required, and timing does not affect results. Antihistamines do not interfere with blood IgE testing, so you do not need to stop them. Bring details of any past reactions and the foods involved, since the result is interpreted against your symptom history.

What this test is for
Clam, crab, lobster, and shrimp are among the most common triggers of food allergy in adults, and shellfish reactions are often lifelong and can be severe, including anaphylaxis. This panel measures IgE antibodies to all four, the antibody class that drives immediate allergic reactions. A positive result means sensitization, not a confirmed allergy: a true allergy requires symptoms that track with exposure, so the result is read against your reaction history. Crab, lobster, and shrimp are crustaceans and often cross-react with each other, while clam is a mollusk, so reactions to one group do not always predict the other.
This panel covers all four shellfish in one draw. If your concern is a single food, the individual Shrimp, Crab, Lobster, or Clam IgE tests pinpoint that one allergen.
Biomarkers tested
Includes 6 biomarkers
- Specimen
- Serum
- Method
- Allergen-specific IgE
- Measures
- Presence / threshold
This test measures IgE antibodies specific to crab, the immune system's flag for a shellfish allergy. When you eat crab, these antibodies trigger mast cells to release histamine, producing hives, swelling, stomach upset, or in severe cases anaphylaxis, so a positive result explains reactions you've already noticed and confirms crab as the trigger rather than another shellfish or food. It's also useful proactively if you're introducing crab after avoiding it, or want clarity before eating it again after an unexplained reaction at a seafood dinner.

This test measures IgE antibodies specific to lobster, the immune system's flag for a shellfish allergy. When mast cells carry lobster-specific IgE, they release histamine on exposure, driving hives, swelling, gut upset, or in severe cases anaphylaxis. Test this if you've reacted after eating shellfish and want confirmation of lobster specifically, or if you're mapping out cross-reactivity across shrimp, crab, and other crustaceans.

This test measures IgE antibodies specific to shrimp (Pandalus borealis), the immune messengers that flag shrimp proteins as a threat and trigger mast cells to release histamine on exposure. A positive result confirms sensitization and helps explain hives, lip or throat swelling, stomach cramps, or more serious reactions after eating shrimp or other shellfish. It's useful for pinning down a suspected shellfish allergy, distinguishing it from unrelated food intolerances, and deciding whether shrimp needs to come off the menu for good.

Frequently asked questions
View all FAQsHow does pricing work?
Every test shows the member price next to the standard non-member price, so you can see what membership saves you. The member price is our cost, covering the lab and what it takes to run the service. It is never a profit on the test itself. Mito makes its money on the $9 membership, not on marking up your tests. Membership is $9 per month, and any applicable lab order or draw fee is itemized before you pay.
Where do I get tested?
Choose an available partner lab at checkout. If your cart contains multiple blood tests, Mito helps consolidate the eligible tests at one lab when possible. At-home kits and scans follow the collection or appointment process shown on their product page.
Is this eligible for HSA/FSA?
Yes. Eligible tests can be paid for with an HSA or FSA card at checkout.
When will I get my results?
Your results appear in your Mito dashboard after the laboratory completes processing. A clinician then reviews them before your analysis and personalized action plan are finalized. Timing varies by test, and specialty assays and at-home kits may take longer.
Do I need a physician's order?
No. Mito provides the laboratory order when one is required, so you do not need to arrange a separate physician visit before purchasing.
