This Trout Allergy Test uses a blood sample to determine whether or not you are allergic to trout. It’s unlikely to be allergic to only trout and not other types of commonly-eaten fish, so consider taking our Fish Allergy Panel to cover more bases all at once (and save money). To identify this specific allergy, order our Trout Allergy Test today.

How Our Trout Allergy Test Works

For our Trout Allergy Test, simply place your order online and stop by one of our 4000+ nationwide testing facilities at your convenience (no appointments). A member of the center’s staff will collect a small blood sample via the skin prick method, at which point your part of the process is done. 

The sample collection itself takes only a few minutes, and most patients are in and out and about their day in under half an hour. From there, your sample will be processed in a CLIA-certified laboratory, and in as little as 24-72 hours, you’ll have full results regarding your trout intolerance.

Common Trout Allergy Symptoms

Trout are species of freshwater fish in the salmon family. These fish species are an important food for humans, preferred for their nutritional value and the flavor of their flesh. Unfortunately, consuming trout or simply coming into contact with trout may result in allergy symptoms in individuals with allergic sensitivities.

The immune system produces antibodies and histamines to fight the food allergens that it mistakes as invaders, resulting in the symptoms of an allergic reaction. Our trout allergy test is an Immunoglobulin (IgE) blood test. An IgE test detects the presence of allergen-specific antibodies in your blood after being exposed to a food allergen.

Like many other food allergies, trout allergy is a serious health condition that can lead to severe symptoms. Learning to recognize the symptoms of an allergy reaction to trout can help you stay prepared. Common trout allergy symptoms include:

  • Stomach pain
  • Hives
  • Nausea 
  • Vomiting
  • Diarrhea
  • Swollen, watery, or itchy eyes
  • Light-headedness

Keep in mind that individuals may react differently to processed trout, and allergic reactions may be species-specific. While the vast majority of allergic reactions to trout occur when a sensitized individual eats trout, allergic persons can react to touching trout or inhaling the vapor (airborne allergens) from cooking trout.

How to Interpret Your Results

As food allergies become more common1 and allergy tests more widely available, people increasingly have to interpret food allergy test results on their own. Unless you have medical training, the results of your trout allergy test can seem perplexing at first glance. 

It is imperative that you take your time to accurately interpret the results, which will be delivered via our secure online portal. Here, you’ll find a complete list of potential allergens on a chart containing ‘result,’ ‘reference range,’ and ‘flag’ columns. 

The ‘Result’ is a numerical value showing your sensitivity to the allergen. The ‘Reference range’ column denotes the threshold of an allergic reaction. Items in the Flag column can be interpreted as potential allergens. 

What Are the Possible Complications of Trout Allergy?

An allergic reaction to trout can be mild or severe. Although rare, severe allergic reactions to trout have been reported. For instance, trout allergy can trigger a severe reaction known as anaphylaxis, even if a previous reaction was mild. 

Usually, anaphylaxis starts with the same symptoms as a mild allergy but quickly gets worse. Symptoms of anaphylaxis are serious and, if left untreated, may be life-threatening. Symptoms of anaphylaxis include:

  • A sudden, significant drop in blood pressure 
  • Passing out (loss of consciousness) due to the low blood pressure
  • Swelling in the throat, making it difficult to breathe
  • Tightening airways

If you are experiencing an adverse reaction towards trout or any other specific food item, seek immediate medical attention.


  • Yes, an individual can be allergic to certain fish species and not others. One can also be allergic to one or two types of trout, but not all.

  • Yes, one can develop a trout allergy at any time. Even individuals who have previously eaten trout can experience an allergic reaction.

  • Trout allergy symptoms can develop quickly or over a few hours. Usually, the symptoms of an allergic reaction to trout can start within 30 minutes of eating or coming into contact with trout.

  • The easiest way to know if you are allergic to trout is by having a trout allergy test. Specific IgE blood testing is the fastest and most convenient to measure food intolerance, including trout allergy.
