What it measures
- Total IgE — A general measure of allergy-related antibodies in your blood.
- Shellfish-specific IgE — Antibodies that target proteins from shellfish such as shrimp, crab, lobster, or clam.
- Shrimp-specific IgE — A common marker because shrimp is a frequent trigger.
- Crab-specific IgE — Checks for antibodies that may react to crab proteins.
- Lobster-specific IgE — Checks for antibodies that may react to lobster proteins.
- Clam or mollusk-specific IgE — Checks for antibodies that may react to mollusks like clams or mussels.
Preparation
No fasting is required for this blood test. Tell your clinician about any medications you take, especially antihistamines, because they may affect some allergy tests.
Results and what they mean
Results are reported as a number for each shellfish allergen, often with a reference range or class. A clinician interprets these numbers alongside your symptoms and history; a positive result alone does not always mean you have a true allergy. This is general information, not medical advice.
