What it measures

- Cross-reactive shellfish markers — Proteins shared with shrimp, lobster, or other shellfish that may cause similar reactions.

Frequently asked questions
Do I need to avoid eating crab before the test?
No, you do not need to avoid crab before this blood test. The test measures antibodies already present in your blood.
Can this test tell me how severe my allergy is?
No, the level of antibodies does not always match how severe a reaction will be. Your clinician will consider your symptoms.
What if my result is positive but I have never had symptoms?
A positive result alone does not always mean you have an allergy. Your clinician may recommend further evaluation.
How long does it take to get results?
Results are usually available within 1 to 3 business days after the sample is received by the lab.
