Shellfish Allergy test

Shellfish allergy testing typically involves a combination of a medical history review, physical examination, and diagnostic tests, according to the Food Allergy Institute.

The Mayo Clinic notes that allergies to crustaceans are the most common type of seafood allergy, which includes shellfish. They also say that some people are allergic to one type of shellfish while being able to eat others.

What are the common types of shellfish that people are allergic to?

The common types of shellfish that people are allergic to, according to the Food Allergy Institute include:

• Shrimp
• Crab
• Lobster
• Clams
• Oysters
• Mussels
• Scallops
• Squid
• Octopus
• Crayfish

It is important to note that any type of shellfish can potentially cause an allergic reaction, and some people may be allergic to one type of shellfish but not others.

How is shellfish allergy testing performed?

Shellfish allergy testing is performed similarly to other types of allergy testing, with the use of either skin tests or blood tests, according to the Mayo Clinic. Skin tests involve placing a small number of proteins found in a particular shellfish under the skin, and then observing you for a reaction.

Blood tests are also used to detect shellfish allergies by measuring the levels of IgE antibodies in the blood. If the levels of IgE antibodies are high after being exposed to a particular shellfish protein, it indicates an allergic reaction to that shellfish.

When should I get tested for shellfish allergies?

You should consider allergy testing if you experience symptoms of an allergic reaction after being exposed to shellfish or other seafood, according to the Food Allergy Institute.

Additionally, if you have a family history of shellfish allergies, you may be more likely to have allergies to shellfish yourself and should consider getting tested, notes the Food Allergy Institute.

What to expect with shellfish allergy testing

There is usually little to no preparation needed for shellfish allergy testing. Your healthcare provider can provide specific details if there are any special considerations you need to take before testing.

Getting tested for shellfish allergies

Most allergy testing can be done at a healthcare facility such as a hospital, walk-in clinic, urgent care, or primary care office. Your doctor can also make a referral to see an allergist—a physician who specializes in testing for and managing allergies.

If you need help finding allergy testing locations you can use the healthcare provider directory on Solv’s website. Solv allows you to contact providers individually to learn more about their services and allows you to book a same-day or next-day appointment from its website.

Can I get an at-home test for shellfish allergies?

There are many at-home allergy test kits available for purchase, including food allergy and food sensitivity tests. The sample collection varies, depending on the brand of test, and results are usually available within a few days to a few weeks.

It is important to note that while at-home allergy test kits may be convenient, they may not be as accurate as tests performed in a healthcare setting, according to the Mayo Clinic. If you receive a positive result from an at-home test, it is recommended that you follow up with a healthcare provider for confirmation and further evaluation.

Additionally, if you are experiencing severe allergy symptoms it may be more appropriate to get tested in a healthcare setting, where you can discuss your potential treatment options with a healthcare provider, recommends the Mayo Clinic.

Cost of shellfish allergy testing

The cost of allergy testing—including shellfish allergy testing—can vary depending on several factors, including the type of test being performed, the location of the testing facility, and your insurance coverage.

Shellfish allergy tests are typically performed as comprehensive seafood allergy testing, and cost between $70 and $96 per test, according to FindLabTest.com. This range depends on the specific test and the laboratory performing the test.

Symptoms of shellfish allergies

The symptoms of a shellfish allergy can vary from mild to severe, according to the Mayo Clinic. These symptoms include:

• Hives
• Itchy, irritated skin
• Nasal congestion
• Swelling of the lips, face, tongue, throat, or other parts of the body
• Wheezing or trouble breathing
• Coughing and choking or a tight feeling in the throat
• Abdominal pain, diarrhea, nausea, or vomiting
• Dizziness, lightheadedness, or fainting

Additionally, severe shellfish allergies can cause a life-threatening reaction called anaphylaxis. The symptoms of anaphylaxis are:

• A swollen throat or tongue or tightness in the throat (airway constriction) that makes it difficult for you to breathe
• Coughing, choking, or wheezing with trouble breathing
• Severe skin rash, hives, itching, or swelling
• Nausea, vomiting, or diarrhea
• Dizziness, lightheadedness, or fainting
