IgE Food Allergy Advanced Test by Mosaic Diagnostics Vs Radioallergosorbent Testing

In today's world, food allergies have become increasingly common and can cause serious health issues. To effectively manage these allergies, accurate testing is crucial. The two most commonly used methods for diagnosing food allergies are the IgE Food Allergy Advanced Test by Mosaic Diagnostics and Radioallergosorbent testing (RAST).

Understanding Food Allergies: An Overview

Food allergies are a common condition that affects millions of people worldwide. It occurs when the immune system mistakenly identifies certain proteins found in food as harmful invaders. This triggers an immune response, leading to a range of symptoms that can vary in severity.

In individuals with IgE food allergies, the immune system produces an excessive amount of immunoglobulin E (IgE) antibodies in response to specific food allergens. IgE antibodies are a type of antibody that plays a crucial role in triggering allergic reactions.

What is IgE Food Allergy?

IgE food allergy is a specific type of food allergy that involves the production of IgE antibodies in response to certain food allergens. When a person with IgE food allergy consumes a trigger food, their immune system recognizes the allergenic proteins in the food and produces IgE antibodies to fight against them.

These IgE antibodies then bind to mast cells and basophils, which are types of immune cells found throughout the body. When the person is exposed to the trigger food again, the allergenic proteins cross-link the IgE antibodies on the surface of the mast cells and basophils, causing them to release a variety of chemicals, including histamine.

The Role of IgE in Food Allergies

The release of histamine and other chemicals by mast cells and basophils is what leads to the development of allergic symptoms. Histamine, in particular, is responsible for many of the classic allergic symptoms, such as hives, itching, swelling, and redness.

In addition to histamine, other chemicals released during an allergic reaction can also contribute to the symptoms. These chemicals can cause blood vessels to dilate, leading to increased blood flow to the affected area and resulting in swelling and redness. They can also increase the permeability of blood vessels, allowing fluid to leak out and causing swelling.

Furthermore, the release of these chemicals can affect smooth muscles, such as those found in the airways. This can lead to bronchoconstriction, causing difficulty breathing and wheezing. In severe cases, the release of chemicals can trigger a life-threatening allergic reaction known as anaphylaxis.

It is important for individuals with IgE food allergies to be aware of their triggers and take necessary precautions to avoid exposure. This may involve reading food labels carefully, informing others about their allergies, carrying emergency medication (such as epinephrine auto-injectors), and seeking medical attention if an allergic reaction occurs.

Understanding the role of IgE antibodies in food allergies can help individuals better manage their condition and reduce the risk of experiencing severe allergic reactions. By staying informed and taking appropriate measures, individuals with IgE food allergies can lead a safe and fulfilling life.

Radioallergosorbent Testing: The Traditional Method

How Does Radioallergosorbent Testing Work?

Radioallergosorbent Testing (RAST), a widely used method for diagnosing food allergies, detects specific IgE antibodies in a person's blood sample. This test involves mixing the blood sample with allergen extracts and measuring the radioactivity of the IgE antibodies bound to a solid phase.

During the test, the allergen extracts are carefully selected based on the patient's medical history and suspected allergens. These extracts contain proteins from common allergenic substances such as peanuts, tree nuts, milk, eggs, wheat, soy, and shellfish. By exposing the patient's blood sample to these allergens, the test aims to identify the specific IgE antibodies that react to them.

The first step in the RAST procedure is to separate the patient's serum, which contains the IgE antibodies, from the rest of the blood components. This is done through a process called centrifugation, where the blood sample is spun at high speeds to separate the different components based on their density.

Once the serum is obtained, it is mixed with the allergen extracts in small wells or tubes. The mixture is then incubated for a specific period to allow the IgE antibodies to bind to the allergens. This binding process is crucial for the detection of specific allergen sensitivities.

After the incubation, the mixture is transferred onto a solid phase, typically a small disc or a membrane coated with a substance that can capture the IgE antibodies. The solid phase is then washed to remove any unbound components, leaving only the IgE antibodies that have bound to the allergens.

Next, a radioactive substance, such as a radioactive isotope of iodine, is added to the solid phase. This substance attaches to the IgE antibodies, making them detectable through radioactivity. The level of radioactivity is measured using a specialized instrument called a gamma counter.

By quantifying the radioactivity, the test can determine the amount of IgE antibodies bound to the allergens. This information helps in assessing the patient's sensitivities to specific allergens and diagnosing food allergies.

Limitations of Radioallergosorbent Testing

While RAST has been an integral part of diagnosing food allergies for many years, it does have some limitations. RAST may have a lower sensitivity and specificity compared to the IgE Food Allergy Advanced Test. Additionally, cross-reactivity among allergens can sometimes lead to misleading results, causing difficulties in accurately identifying the specific allergen triggers.

One of the limitations of RAST is that it measures the total amount of IgE antibodies bound to the allergens, without distinguishing between different subtypes of IgE antibodies. This means that the test may not provide detailed information about the specific allergenic proteins responsible for the allergic reactions.

Moreover, cross-reactivity can occur when different allergenic proteins share similar structures. For example, a person allergic to birch pollen may also exhibit allergic reactions to certain fruits, such as apples or peaches, due to the presence of similar proteins. RAST may not be able to differentiate between these cross-reactive allergens, leading to potential misinterpretation of the results.

Another limitation is the possibility of false negatives or false positives. False negatives can occur when the test fails to detect the presence of specific IgE antibodies, leading to a misdiagnosis of non-allergic status. On the other hand, false positives can happen when the test indicates the presence of IgE antibodies, but the person does not experience any allergic symptoms when exposed to the suspected allergen.

Despite these limitations, RAST remains a valuable tool in diagnosing food allergies. It provides valuable insights into a person's sensitivities to different allergens, helping healthcare professionals develop appropriate management plans and avoid potential allergic reactions.
