About the Crab Allergy Test - Shellfish Allergy
A crab-specific IgE blood test checks for antibodies the immune system produces against crab proteins. It is a screening tool for suspected shellfish allergy and is not a diagnosis on its own. A healthcare provider may order it after a reaction to crab or other crustaceans, or as part of a broader shellfish panel. Because crab shares proteins with shrimp and lobster, the result is often interpreted alongside those related crustacean markers.
Who this test may be right for
- People who develop hives, itching, or swelling after eating crab
- Individuals with mouth tingling or throat irritation after crustaceans
- Those with digestive upset, vomiting, or diarrhea after crab
- People with eczema or skin reactions who suspect a seafood trigger
- Anyone with a history of reaction to crab or other shellfish
What this test measures
- Crab-specific IgE Antibodies produced in response to crab proteins; used to assess sensitization to crab.
Before your visit
- No fasting is required for this IgE allergy test
- The blood sample can be collected at any time
- Tell the provider about medications you take
- No special diet is needed beforehand
Understanding your results
The crab-specific IgE result is reported as a numeric level or class. A value above the reporting threshold may indicate sensitization to crab proteins, but sensitization does not always lead to symptoms. A low or undetectable level makes a true crab allergy less likely without completely ruling it out. Crab shares a muscle protein with shrimp and lobster, so a provider may consider cross-reactivity among crustaceans. Discuss results with a healthcare provider before changing your diet.
