Order Shellfish Allergy Test - Crab, Shrimp, Clam, LobsterShellfish allergies rank among the most common food allergies in adults, and reactions can range from mild itching to severe anaphylaxis. Because different shellfish belong to distinct biological groups, a reaction to shrimp does not automatically mean a reaction to clams. This panel measures specific IgE antibodies against four frequently eaten shellfish—crab, shrimp, clam, and lobster—to help clarify which ones may trigger an immune response.
About Shellfish Allergy Test - Crab, Shrimp, Clam, Lobster in Cambridge
Specific IgE testing offers an objective look at sensitization to individual shellfish species.
The immune system can mistakenly identify proteins in shellfish as threats and produce immunoglobulin E (IgE) antibodies against them. When those proteins are encountered again, the antibodies can trigger the release of histamine and other chemicals, producing symptoms such as hives, swelling, digestive upset, or breathing difficulty. A blood test detects the presence of these antibodies without exposing a person to the food itself.
Crab, shrimp, clam, and lobster are grouped here because they represent both major shellfish categories: crustaceans (crab, shrimp, lobster) and mollusks (clam). Crustacean allergies are more frequently diagnosed, but mollusk allergies also occur and can be overlooked. Testing each species separately helps distinguish a broad sensitivity from a reaction tied to one particular type of seafood.
Results are reported as antibody levels for each shellfish. A positive result indicates sensitization, which does not always equate to a clinical allergy; some people have detectable IgE without symptoms. Conversely, a negative result makes allergy less likely but does not entirely rule it out. Physicians interpret these values alongside a person's history, symptoms, and other findings to reach a diagnosis.
