Order Crab Allergy Test | Shellfish AllergyA crab allergy test measures the amount of crab-specific immunoglobulin E (IgE) in the blood.

About Crab Allergy Test | Shellfish Allergy in Fallbrook
Crab allergy is one of the more common shellfish allergies and can cause reactions ranging from mild to severe.
Crab belongs to the crustacean group of shellfish, which also includes shrimp, lobster, and crayfish. Allergic reactions occur when the immune system identifies proteins in crab as harmful and releases chemicals such as histamine. Symptoms may include hives, itching, swelling of the lips or tongue, stomach upset, wheezing, or difficulty breathing.
A blood test detects crab-specific IgE antibodies without exposing the person to crab. Because sensitization does not always equal clinical allergy, results are interpreted together with a person's history of reactions. Some individuals with a positive result may tolerate crab, while others with a negative result may still react under certain conditions.
Crab allergens can be present in steamed, boiled, fried, and processed foods, and cross-contact during cooking is a known concern. Tropomyosin, a muscle protein, is a major crab allergen and is also found in other crustaceans and mollusks, which is why reactions to more than one type of shellfish are possible. A healthcare professional can explain what a given result means for an individual.
