Order Shellfish Allergy Test - Crab, Shrimp, Clam, LobsterShellfish allergies are among the most common food allergies in adults, and reactions can range from mild oral itching to severe systemic responses. Because different shellfish species contain distinct proteins, a person may react to one type and tolerate another. This panel measures specific IgE antibodies against four representative shellfish: crab, shrimp, clam, and lobster.
About Shellfish Allergy Test - Crab, Shrimp, Clam, Lobster in Highland
Specific IgE blood testing helps identify sensitization to individual shellfish species.
The immune system can produce IgE antibodies against proteins found in crustaceans and mollusks. Crustaceans such as shrimp, crab, and lobster share tropomyosin, a protein that often causes cross-reactivity. Clams, as mollusks, contain different allergenic proteins, so reactivity patterns can vary.
A blood sample is analyzed for IgE antibodies binding to each of the four shellfish extracts. Results are reported as quantitative values that indicate the likelihood and degree of sensitization. A positive result does not by itself diagnose a clinical allergy; it must be interpreted alongside a person's history of reactions.
This panel is useful when a clinical history suggests shellfish allergy, when skin testing is not feasible, or when a clinician wants to assess reactivity to multiple species at once. Results can guide avoidance strategies and inform whether further evaluation, such as oral food challenge, may be appropriate.
