Order Crab Allergy Test | Shellfish AllergyA crab allergy test measures the amount of specific IgE antibodies in the blood that react to crab proteins. This type of testing helps identify whether an immune response to crab is present, which is useful when symptoms suggest a shellfish allergy.
About Crab Allergy Test | Shellfish Allergy in Fremont
Crab allergy testing focuses on the immune system's response to proteins found in crab.
Crab is a crustacean, and crustacean shellfish include crab, shrimp, lobster, and crayfish. Allergic reactions to crab occur when the immune system identifies certain proteins in the shellfish as harmful and produces immunoglobulin E, or IgE, antibodies against them.
The test uses a blood sample to measure crab-specific IgE. A laboratory adds the sample to a preparation containing crab allergen and detects whether IgE antibodies bind to it. The result is reported as a numerical value or class, which a healthcare provider interprets alongside symptoms and history.
A positive result indicates sensitization to crab, meaning IgE antibodies are present. It does not by itself confirm that a clinical allergy will occur, and a negative result does not always rule out allergy. Diagnosis depends on the combination of test results, symptom history, and clinical judgment.
