About Crawfish Allergy Test | Shellfish Allergy in Berkeley
Crawfish allergy testing evaluates the immune system's antibody response to crawfish proteins using a blood sample.
The test detects IgE antibodies that bind to proteins found in crawfish. When the immune system has previously been sensitized to these proteins, IgE antibodies can be present in the bloodstream and are identified through a laboratory immunoassay.
Crawfish are crustaceans, a subgroup of shellfish that also includes shrimp, crab, and lobster. Proteins such as tropomyosin are shared across many crustacean species, so a positive result to crawfish may indicate cross-reactivity with other shellfish rather than a reaction limited to crawfish alone.
Results are reported as a quantitative antibody level and should be interpreted alongside clinical history. A detectable IgE level indicates sensitization, not necessarily a clinical allergy, and a physician can help determine what the findings mean in the context of symptoms and dietary exposure.
