The crab allergy test is a blood test that checks for an allergic sensitization to crab proteins. It is usually ordered when a person has had allergic symptoms after eating crab or other shellfish, or when a doctor needs to confirm or rule out a crab allergy.
What it measures
- Crab-specific IgE antibodies — Antibodies made by the immune system that bind to crab proteins.
- Total IgE — A general measure of allergic antibody levels, sometimes used for context.
- Cross-reactive shellfish markers — Proteins shared with shrimp, lobster, or other shellfish that may cause similar reactions.
Who it is for
This test is typically ordered by an allergist, immunologist, or primary care clinician for people who have had symptoms like hives, swelling, or breathing trouble after eating crab or other shellfish.
Preparation
No fasting or special preparation is needed. Tell your clinician about any medications you take, especially antihistamines, as they may affect test results.
Results and what they mean
Results are reported as a level of crab-specific IgE antibodies, often with a reference range. A clinician interprets the result along with your symptoms and history. This information is general and not medical advice; only a qualified healthcare professional can diagnose a crab allergy.

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.
