Seafood Allergy test

Seafood 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. They also say that some people are allergic to one type of seafood while being able to eat others.

How is seafood allergy testing performed?

Seafood allergy testing can be done with either skin tests or blood tests, according to the Mayo Clinic. Skin tests involve placing a small number of proteins found in a particular seafood under the skin, and then observing you for a reaction. Blood tests can also be used to detect seafood allergies by measuring the levels of IgE antibodies in the blood. If the levels of IgE antibodies are high after being exposed to a seafood protein, it indicates an allergic reaction to seafood.

When should I get tested for seafood allergies?

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

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

What to expect with seafood allergy testing

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

Getting tested for seafood 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.

Can I get an at-home test for seafood 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. 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, the Food Allergy Institute notes that it is more appropriate to get tested in a healthcare setting, where you can discuss your potential treatment options with a healthcare provider.

Cost of seafood allergy testing

The cost of allergy testing—including seafood 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.

Seafood allergy tests typically cost between $97 and $136 per test, according to FindLabTest.com. The cost depends on the specific test and the laboratory performing the test.

Symptoms of seafood allergies

The symptoms of seafood allergies 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

Additionally, severe seafood 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
