About Crab Allergy Test | Shellfish Allergy in Fallbrook
The crab allergy test is a blood-based immunoassay that quantifies IgE antibodies directed against crab allergens.
IgE antibodies are part of the immune system's response to substances it identifies as threats. When a person is sensitized to crab proteins, their immune system may produce IgE antibodies that bind to those proteins. A blood test can detect and measure these antibodies to assess sensitization.
Crab is a crustacean, and its proteins can cross-react with those of other shellfish such as shrimp, lobster, and crayfish. Because of this, a crab allergy test is often part of a broader evaluation for shellfish allergy. The test does not diagnose an allergy on its own; it provides objective data that a clinician interprets alongside symptoms, medical history, and other findings.
Results are reported as a numerical value or a class score indicating the level of crab-specific IgE. Higher levels generally suggest a greater likelihood of clinical reactivity, but the presence of IgE alone does not confirm that a reaction will occur. Some individuals with detectable antibodies may tolerate crab, while others with low levels may still react. Therefore, test results should be reviewed by a qualified healthcare professional.
