Shellfish Allergy Test in Connecticut

A shellfish allergy test checks your blood for antibodies that may react to proteins found in shellfish. It is usually ordered when someone has had allergic symptoms after eating shellfish, or when a clinician wants to confirm or rule out a shellfish allergy.

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.

Who it is for

A primary care clinician, allergist, or other healthcare professional typically orders this test. It may be ordered for adults or children with suspected reactions to shellfish.

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.
