Shrimp Antibody Test
A shrimp allergy test measures IgE antibodies to shrimp proteins in a blood sample. Shrimp is a common crustacean allergen and a frequent trigger of food reactions.

Quick answer
The shrimp allergy test is a blood test that measures immunoglobulin E antibodies against shrimp proteins. Shrimp is one of the most common shellfish allergens, and reactions can range from itching and hives to stomach symptoms and more serious responses. The test helps assess whether a person has become sensitized to shrimp. A healthcare provider interprets the result with the clinical history and any history of reactions.
What this test measures
Shrimp is a crustacean, and its proteins can act as potent allergens. Tropomyosin is the best-known shrimp allergen, and it is heat-stable, meaning reactions can occur even with fully cooked shrimp. Symptoms may include hives, swelling, stomach upset, or breathing difficulty. Because shellfish are frequently eaten and sometimes hard to avoid, testing is a common part of food allergy evaluation.
The test measures shrimp-specific IgE in a serum sample and reports a quantitative level or reactivity class. It can be ordered on its own or as part of a broader shellfish panel. Results reflect sensitization to shrimp proteins and are considered together with the timing and nature of any symptoms after eating shrimp or related crustaceans.
A positive result does not automatically mean a reaction will occur, and a negative result does not always rule out allergy. The test is one piece of the clinical picture. Anyone with concerns about shellfish reactions should speak with a qualified healthcare provider, especially if past reactions were severe.
- Shrimp-specific IgE antibodies
- Total serum IgE
- Quantitative allergen-specific IgE level
- IgE reactivity class for shrimp
- Tropomyosin reactivity when available
- Cross-reactive crustacean allergens when included
Why people order this test
- Investigate symptoms after eating shrimp or related crustaceans
- Assess sensitization as part of a shellfish allergy workup
- Support evaluation of hives, swelling, or stomach symptoms after seafood
- Clarify reactivity when multiple shellfish are suspected
- Provide objective data before a provider discusses avoidance
How to prepare
No fasting is required for this blood test. A sample is collected from a vein, usually at the arm. Follow any specific instructions provided by the laboratory.
Understanding your results
Results are typically reported within one to three business days. The report shows the shrimp-specific IgE level or class. An elevated result suggests sensitization to shrimp, and a healthcare provider explains what it means for the individual.

Frequently Asked Questions
What is tropomyosin?
Tropomyosin is a protein found in crustaceans and is a major shrimp allergen. It is heat-stable, so cooking does not reliably remove it.
How is the test performed?
A small blood sample is drawn from a vein and analyzed for IgE antibodies that react to shrimp proteins.
Do I need to fast?
No fasting is required unless the test is ordered with other tests that need it.
Can I be allergic to shrimp but not other shellfish?
Yes. Sensitization can be specific to shrimp or can extend to other crustaceans. Testing several species helps clarify the pattern.
Does a negative result rule out shrimp allergy?
No. A negative test does not fully rule out allergy. A healthcare provider interprets the result with the clinical history.
