About Our Crayfish (Crawfish) Allergy Test

Note: Fasting is not required for this test.

This IgE antibody allergy test uses a blood sample to determine if you are allergic to Crayfish.

Crayfish (also called crawfish, crawdads, mudbugs, freshwater lobsters, mountain lobsters, poor man's lobsters, and yabbies) are freshwater crustaceans similar in appearance to lobsters, but much smaller. Crayfish live in freshwater sources, such as streams, rivers, ponds, and lakes. They reside under rocks and feed on animals or plants (decomposing and living) that exist on the bottom of their habitats. 

Crayfish are a type of shellfish, and an allergy to crayfish indicates a likely reaction to other crustaceans. Seafood in crustaceans category include shrimp, lobster, crab, barnacle, krill, and prawns. A crayfish allergy doesn't necessarily mean an allergy to mollusks, which are seafood like clams, oysters, and mussels. If you'd like to receive a more comprehensive allergy test, check out our shellfish allergy test.

Crayfish allergic reactions include the following:

  • Hives (raised skin bumps)
  • Swelling of the lips/face
  • Tingling in the throat/mouth
  • Itchy skin rash
  • Runny nose
  • Itchy, watery eyes
  • Tightening of the throat
  • Anaphylaxis

Allergic reactions to shellfish tend to be severe, so if you believe you have an allergy, it's best to get tested and know for certain!
