IgE Food Allergy Basic Test by Mosaic Diagnostics Vs Skin Prick Test
In the world of healthcare, there are various tests available to determine if individuals have allergies to specific foods. Two common tests used for this purpose are the IgE Food Allergy Basic Test by Mosaic Diagnostics and the Skin Prick Test. Understanding the differences between these tests and their respective benefits is crucial when it comes to making informed decisions about food allergy testing.
Understanding Food Allergies
In order to comprehend the significance of these allergy tests, it is important to understand the nature of food allergies themselves. A food allergy is an immune system response to a specific food or ingredient that the body mistakenly perceives as harmful. This triggers an allergic reaction which can range from mild discomfort to severe and life-threatening symptoms. It is estimated that approximately 4% of adults and 5% of children have food allergies.
Food allergies can be a complex and challenging condition to manage. They can develop at any age, and while some children outgrow their allergies, others may have them for a lifetime. The symptoms of food allergies can vary widely from person to person, making diagnosis and treatment a unique process for each individual.
What is a Food Allergy?
A food allergy occurs when the immune system mistakenly identifies harmless proteins in certain foods as a threat. This triggers the release of IgE antibodies, which then cause the release of histamine and other chemicals within the body. The allergic reaction can manifest in various ways, such as hives, swelling, digestive issues, respiratory problems, and even anaphylaxis in severe cases.
When a person with a food allergy comes into contact with the allergen, their immune system goes into overdrive, releasing chemicals that can affect different organs and systems in the body. This immune response can occur within minutes or up to a few hours after consuming the allergenic food.
Common Food Allergens
There are several common food allergens that trigger allergic reactions in individuals. These include peanuts, tree nuts, eggs, milk, soy, wheat, fish, and shellfish. These allergens are particularly problematic as they often appear in many different types of foods, making it challenging for individuals with allergies to avoid them entirely.
Peanuts and tree nuts, such as almonds, cashews, and walnuts, are among the most common food allergens. They can cause severe reactions in some individuals, even in tiny amounts. Eggs and milk are also common allergens, especially in young children. Soy, wheat, fish, and shellfish allergies are also prevalent and can cause significant discomfort and health complications.
It is important to note that food allergies can vary in severity. While some individuals may only experience mild symptoms, such as an itchy mouth or hives, others may develop more severe reactions, such as difficulty breathing or a drop in blood pressure. Anaphylaxis, a severe and potentially life-threatening allergic reaction, can occur in some cases and requires immediate medical attention.
Managing food allergies involves strict avoidance of the allergenic foods and being prepared for accidental exposure. Many individuals with food allergies carry epinephrine auto-injectors, such as EpiPens, to use in case of an emergency. Education and awareness about food allergies are crucial in ensuring the safety and well-being of individuals with these conditions.

Introduction to the Skin Prick Test
The Skin Prick Test is another commonly used method to diagnose food allergies. It involves exposing the skin to small amounts of allergens and observing the body's reaction. This test is often performed on the forearm or back, using a panel of allergens related to food allergies.
Food allergies can cause a range of symptoms, from mild discomfort to severe reactions such as anaphylaxis. Identifying specific food allergies is crucial for individuals to manage their condition effectively and avoid potential life-threatening situations. The Skin Prick Test offers a quick and reliable way to determine which allergens trigger an immune response in the body.
When a person consumes a food they are allergic to, their immune system recognizes certain proteins in the food as harmful and mounts an immune response. This response involves the release of histamines and other chemicals, leading to the symptoms associated with allergies. The Skin Prick Test capitalizes on this immune response to identify the specific allergens causing the reaction.
The Procedure of the Skin Prick Test
During the Skin Prick Test, small drops of allergen extracts are placed on the skin, after which a tiny needle is used to prick or scratch the skin's surface. This allows for the allergens to enter and interact with the immune system. The healthcare provider will then monitor the skin for any signs of an allergic reaction, such as redness, swelling, or a raised bump known as a wheal.
The panel of allergens used in the test may include common food allergens such as peanuts, tree nuts, milk, eggs, wheat, soy, and shellfish. These allergens are carefully selected based on their prevalence and potential to cause severe allergic reactions. The extracts used are highly purified to ensure accurate results and minimize the risk of cross-reactivity.
After the allergens are applied to the skin, the healthcare provider will wait for a specific period of time, usually around 15 to 20 minutes, to allow the immune system to react. During this waiting period, the patient may experience mild itching or discomfort at the test site. It is important to remain still and avoid scratching or rubbing the area to prevent any interference with the test results.
Pros and Cons of the Skin Prick Test
One of the advantages of the Skin Prick Test is its speed and simplicity. The results are typically available within 15 to 20 minutes, allowing for immediate assessment. This quick turnaround time enables healthcare providers to promptly determine the presence of specific food allergies and guide patients in avoiding those allergens.
In addition to its speed, the Skin Prick Test is generally well-tolerated and does not require any specialized equipment or extensive preparation. It is a relatively non-invasive procedure, making it suitable for both children and adults. The simplicity of the test also allows for easy replication, ensuring consistent and reliable results.
However, there are also downsides to consider. The Skin Prick Test may cause discomfort during the procedure, as the skin is pricked or scratched. Some individuals may experience mild pain or itching at the test site, although these symptoms are usually temporary and subside quickly.
Another limitation of the Skin Prick Test is the potential for false positives and false negatives. A false positive occurs when the test indicates an allergic reaction to an allergen that the person can actually tolerate without any adverse effects. On the other hand, a false negative occurs when the test fails to detect an allergy that the person does have, resulting in a missed diagnosis.
It is important to note that the Skin Prick Test may not be suitable for everyone. Individuals with certain skin conditions, such as eczema or psoriasis, may have compromised skin barrier function, which can affect the accuracy of the test results. Additionally, certain medications, such as antihistamines, can interfere with the immune response and potentially lead to false-negative results. It is essential to inform the healthcare provider about any medications or skin conditions before undergoing the Skin Prick Test.
In conclusion, the Skin Prick Test is a valuable tool in diagnosing food allergies. Its simplicity, speed, and reliable results make it a preferred choice for healthcare providers. By identifying specific allergens, individuals can take necessary precautions, such as avoiding certain foods or carrying emergency medication, to manage their food allergies effectively and minimize the risk of severe reactions.
