Order Crab Allergy Test | Shellfish AllergyCrab allergy testing measures the amount of immunoglobulin E (IgE) antibodies your immune system produces in response to crab proteins. Because crab belongs to the crustacean family of shellfish, a reaction to it often signals sensitivity to related species such as shrimp, lobster, and crayfish. This blood-based test offers a clear, objective way to assess that sensitivity without exposing you to the food itself.
About Crab Allergy Test | Shellfish Allergy in San Francisco
Crab is one of the most common triggers of shellfish allergy, and reactions can range from mild to severe.
Crab allergy occurs when the immune system mistakenly identifies proteins in crab—most notably tropomyosin—as harmful and releases IgE antibodies to defend against them. Those antibodies attach to immune cells, and a subsequent exposure can prompt the release of histamine and other chemicals that cause symptoms.
A crab allergy test detects the presence and level of crab-specific IgE in the bloodstream. It is typically used alongside a clinical history to help confirm a suspected allergy, especially when skin testing is impractical or when a person cannot safely undergo an oral food challenge.
Shellfish allergies are often lifelong, and crab sensitivity frequently overlaps with reactions to other crustaceans. Because even small amounts can trigger a response in highly sensitive individuals, identifying the allergy through testing helps guide avoidance and informs discussions with a healthcare provider about management.
