Also Known As:
Allergen Profile, Food-Shellfish, Quantitative Allergen-specific IgE Test (Shellfish)
Purpose of the Shellfish Allergy Test
The shellfish allergy panel helps confirm food allergies against clam, crab, lobster, oyster, scallop, shrimp, and other shellfish. It is also required to assess allergic sensitivity, laying the foundation for immunotherapy. Those who take medications also opt to take the test, especially if the response to the condition is below expectations.
Crab (f23) IgE (2823)
Lobster (f80) IgE (2855)
Oyster (f290) IgE (8932)
Scallop (f338) IgE (273)
Shrimp (f24) IgE (2824)
What Does the Shellfish Allergy Panel Measure?
Shellfish allergy testing screens for immunoglobulin E (IgE) – an antibody released by the immune system when an allergen enters the bloodstream. Allergens are harmless substances incorrectly marked as dangerous elements by the immune system.
In the case of shellfish allergy, the allergen is typically a muscle protein commonly found in shellfish called tropomyosin. Thus, eating shellfish increases IgE, making this antibody a perfect marker for the immune response.
Standard tests included in a shellfish allergy panel include the following:
- Shrimp Allergy Test
- Lobster Allergy Test
- Crab Allergy Test
- Clam Allergy Test
- Oyster Allergy Test
- Scallop Allergy Test
Who Should Take a Blood Test for Shellfish Allergy?
Those who repeatedly exhibit allergy symptoms for over two weeks should take an allergy blood test. If the allergic reaction is triggered after eating shellfish or mollusks, inform your doctor to confirm the medical connection.
Shellfish allergy symptoms you should watch out for include:
- Stuffy nose
- Watery eyes
- Abdominal cramps
- Throat tightness
- Nausea and vomiting
- Coughing and choking
- Sneezing and wheezing
- Skin rashes and itchiness
- Dizziness and lightheadedness
- Swollen lips, face, tongue, and other body parts
Withholding testing increases your risk of anaphylaxis, a life-threatening shock caused by allergies. This results in low blood pressure, weak pulse, breathing difficulty, narrow airways, severe digestive distress, rapid skin rash, and even death. Thus, consult your doctor at the onset of allergy symptoms.
Shellfish Allergy Test Preparation
No special preparation is needed before blood sample collection.
Shellfish Allergy Test Panel Results
The IgE test for shellfish allergy not only detects the antibodies but measures them as well. The test report uses reference intervals to show how high IgE is for a specific shellfish.
For example, when taking a Labcorp Allergen Profile for shellfish, the normal level of IgE is less than 0.10 kU/L. Exceeding this value helps verify the allergy and the specific result also falls under a particular class which determines the severity of the condition.
