When is a Food Allergy test ordered?

When a person exhibits symptoms or signs that point to an allergy to one or more substances, one or more tests for the allergen-specific IgE antibodies are typically requested. Some warning signs and symptoms include:

  • Hives
  • Dermatitis
  • Eczema
  • Angry red eyes
  • nasal congestion, sneezing, and coughing
  • Asthma
  • tongue tingling and scratching
  • stomach aches, nausea, or diarrhea

On occasion, a test may also be requested to assess the efficacy of immunotherapy or identify whether a child has outgrown an allergy.

What does a Food Allergy blood test check for?

A family of antibodies called immunoglobulin E is connected to allergic responses. Normally, blood only contains very trace levels of it. In order to identify an allergy to a specific substance, this test quantifies the level of allergen-specific IgE in the blood.

The immune system of the body, which serves as its line of defense against “intruders,” includes the antibody IgE. A person who is predisposed to allergies becomes sensitized the first time they are exposed to a potential allergen, such as food, grass, or animal dander. When a person is exposed to a potential allergen, their body reacts by producing a particular IgE antibody that attaches to basophils in the circulation as well as specialized mast cells in their skin, respiratory system, and gastrointestinal tract. The allergic reaction starts at the location of the next exposure when these associated IgE antibodies recognize the allergen and stimulate the mast and basophil cells to release histamine and other chemicals in response.

Honeybee against bumblebee, egg white versus egg yolk, and gigantic ragweed versus western ragweed are just a few examples of the allergen-specific IgE antibody tests that have been conducted. These tests can be grouped together as food panels or regional weed, grass, and mold panels, for example. Alternately, the medical professional may choose and choose from a lengthy list of specific allergens that are thought to be the source of a person’s allergies.

The RAST radioallergosorbent test, whichh was once the standard procedure for blood testing, has been replaced by more recent IgE-specific immunoassay techniques.

This specific Food Allergy Profile tests for the following IgE antibodies:

  • Almond (f20)
  • Cashew Nut (f202)
  • Codfish (f3)
  • Cow’s Milk (f2)
  • Egg White (f1)
  • Hazelnut (f17)
  • Peanut (f13)
  • Salmon (f41)
  • Scallop (f338)
  • Sesame Seed (f10)
  • Shrimp (f24)
  • Soybean (f14)
  • Tuna (f40)
  • Walnut (f256)
  • Wheat (f4)

Lab tests often ordered with a Food Allergy test:

  • Complete Blood Count (CBC)
  • Total IgE
  • Histamine
  • Tryptase

Conditions where a Food Allergy test is recommended:

  • Allergies
  • Asthma

How does my health care provider use a Food Allergy test?

When a person exhibits acute or persistent allergy-like symptoms, a blood test called the allergen-specific IgE antibody test can assist determine whether they are allergic to a particular drug or substances. This is especially true if additional family members are known to have allergies and if symptoms are persistent and seem to be linked to triggers, such as exposure to specific foods or settings.

By exposing a person to various substances while being closely monitored by a medical professional, several sorts of allergy testing can be carried out. However, some skin disorders, such as severe dermatitis or eczema, as well as some drugs, such as histamines and some anti-depressants, can impair the effectiveness of these tests. There is also a chance for severe reactions, including ones that could be fatal, like anaphylaxis, with some testing. The allergen-specific IgE antibody test may be requested as an alternative in these circumstances because it is carried out on a blood sample and has no effect on the person being examined.

The allergen-specific IgE antibody test can help determine whether a child has outgrown an allergy or whether immunotherapy is working. The degree of IgE present does not correspond to the intensity of an allergic reaction, and someone who has outgrown an allergy may continue to have positive IgE for many years thereafter, therefore it can only be used in a generic sense.

What do my Food Allergy test results mean?

Blood tests for allergies must be read carefully. There is a slight possibility that a person does in fact have an allergy even if an IgE test is negative. A person may or may not ever experience an actual physical allergic reaction when exposed to that substance if the specific IgE test is positive.

Negative findings suggest that a person is most likely not allergic, as defined by an IgE-mediated reaction to the particular allergens tested.

A high allergen-specific IgE result suggests that the subject is probably allergic. The quantity of particular IgE present, however, does not always indicate how severe a reaction can be. To confirm an allergy diagnosis, a person's clinical background and additional medically-supervised allergy testing may be required.

We advise having your results reviewed by a licensed medical healthcare professional for proper interpretation of your results.

Immunoassay (IA)

The ImmunoCAP® Peanut Component Allergen Test helps to assess a patient's level of risk of a life-threatening reaction, and may reassure patients when the risk for allergic symptoms is low or when they will most likely experience mild or localized reactions upon exposure to peanut. The test helps the health care provider identify primary, species-specific allergic sensitization, differentiate between symptoms caused by a primary allergen source and those caused by cross-reactivity, assess the level of risk for life-threatening allergic reactions, and provide clarity regarding the patient's risk of an allergic reaction to ease fears and help target effective management.

Food allergies affect 32 million Americans. It's estimated that every three minutes, a food allergy sends someone to the emergency room.

If you suspect you have a food allergy, it's important to know just what you're allergic to, so you can take steps to avoid coming into contact with that food. Wondering what foods you should avoid?

To learn about your allergies, it's essential to undergo a food allergy test. This article will go over some food allergy basics and what you need to know about testing. Keep reading to learn more.  

What Are Food Allergies?

Any food can cause an allergy response. Allergies can start in childhood or develop later in life. But, no matter the allergy, there's one commonality: food allergies are potentially life-threatening. 

The severity of a food reaction varies. A mild reaction usually involves minor abdominal pain or hives. Severe reactions can cause low blood pressure, anaphylaxis, and loss of consciousness. 

While there are no cures for food allergies, they may go away with time. It depends on several factors, including a person's health and exposure to the allergen. However, there are ways to monitor food allergies safely.  

What Causes Food Allergies?

Food allergies occur when the immune system mistakes proteins found in food as a threat. As a result, chemicals are released throughout the body, which causes the symptoms of allergic reactions. 

While nearly any food can cause a reaction, some are more common than others. For example, the most common food allergens in the United States include: 

  • Milk 
  • Egg
  • Peanut 
  • Tree nuts 
  • Soy 
  • Wheat 
  • Fish 
  • Shellfish 

Even though we're aware of how food allergies happen, it's unclear why people develop allergies to certain food. Those with common food allergies tend to have other allergic conditions like asthma and eczema. 

Doctors divide food allergies into three types. The categories are based on the symptoms, as well as when they occur. 

The first type is IgE-mediate food allergies. This is the most common type, and it's triggered by the immune system producing immunoglobulin E. There is an increased risk of anaphylaxis with this type of allergy. 

Next, we have non-IgE-mediated food allergies. The allergic reaction is caused by other cells in the immune system. Symptoms take hours to appear, as opposed to minutes. 

The final type is mixed IgE and non-IgE-mediate food allergies. This is a combination of the two allergy types discussed above. 

Signs and Symptoms of a Food Allergy 

If you or someone you know has a food allergy, it's important to recognize the signs and symptoms of a reaction. This way, you can seek medical attention as soon as possible. 

Within a few minutes or hours of eating a food you're allergic to, you're likely to experience:

  • Itching 
  • Hives 
  • Swelling
  • Wheezing 
  • Abdominal pain 
  • Dizziness 

Depending on your degree of reaction and how familiar you are with treating your allergy, you may only need to take medication and follow up with your doctor. 

With a severe allergy that causes anaphylaxis, emergency treatment is crucial. If left untreated, anaphylaxis can cause coma or death. Some of the signs include a drop in blood pressure, a rapid pulse, tightening of the airways, and loss of consciousness.

Types of Food Allergy Testing 

There are several options when it comes to food allergy lab tests. You can decide what's best for you based on your doctor's opinion and your own experiences.

Oral Challenge Test 

An allergist will give you small amounts of the food you suspect are causing your allergy. The food could be administered in an ingestible capsule or via injection. The allergist will watch you closely after administering the food and provide treatment if you react. 

Elimination Diet 

If you think you know what foods are causing allergic reactions, you can start eliminating them from your diet. Then, you start to add them back into your diet, one by one, to see if you react. This is not recommended if you are at risk for a severe allergic reaction. 

Skin Prick Test 

An allergist will put a small amount of the suspected food on your skin. Then, they will prick the skin with a needle to let the food enter your system. If you develop hives at the injection site, you're probably allergic. 

Blood Test 

While the other tests involve consuming or coming into contact with the food you may be allergic to; a blood test does not require you to experience an allergic reaction. Instead, a medical professional will take a blood sample for a food allergy lab test, usually from your arm, and test for IgE substances. 

Food allergy test results usually come back within one to three days. From there, you and your doctor can plan a treatment course. 

The Benefits of a Food Allergy Test  

For optimal health, it's important to undergo food allergy testing if you are worried about allergic reactions. While there's no way to cure your allergy, you'll know what to eliminate from your diet, so you don't get sick. 

You'll also be aware of the type of allergic reaction you have and what you need to do to manage it. For example, you can keep medication, like an EpiPen, on your person, or you'll know that you need to take a trip to the emergency room to avoid complications.
