The Food Allergy and Sensitivity Testing (FAST 88 Foods: IgE, IgG4, IgG, C3b/d) offered by Infinite Allergy Labs is a comprehensive assessment tool designed to identify adverse reactions to a wide range of food antigens.
This test analyzes various immunoglobulins (IgE, IgG4, IgG) as well as complement activation products (C3b/d), providing a thorough assessment of the immune response to 88 common food allergens. By measuring multiple immune markers, including both immediate (IgE) and delayed (IgG, IgG4) hypersensitivity reactions, as well as complement activation, this test offers a comprehensive understanding of the body's immune reactivity to different foods. [18.]
For patients, this test can offer insights into their individual sensitivities and intolerances, helping them identify specific dietary triggers contributing to various health issues such as digestive problems, skin disorders, autoimmune conditions, and chronic inflammation.
Additionally, by pinpointing potential food allergens, patients can make informed dietary modifications to alleviate symptoms and improve overall well-being. For medical providers, the FAST 88 Foods test provides a valuable tool for identifying food sensitivities and allergies, guiding personalized treatment plans, and optimizing patient care.
This comprehensive approach to food allergy testing empowers both patients and healthcare providers to address underlying immune imbalances and promote better health outcomes.
Environmental Allergy Test (88 Antigen IgE) By Infinite Allergy Labs:
The 88 Antigen IgE Environmental Panel by Infinite Allergy Labs provides a comprehensive and less invasive alternative to traditional skin prick allergy testing. Unlike skin prick tests, which can be uncomfortable and expose patients directly to potential allergens, serum allergy testing requires only one blood sample to test multiple allergens.
Infinite Allergy Labs' Environmental Allergy Panel covers 88 common allergens, offering a thorough assessment of environmental triggers that may contribute to allergic reactions. Understanding the distinction between seasonal and perennial allergies is crucial, as seasonal allergies are typically triggered by outdoor allergens like pollen and mold spores, whereas perennial allergies are often caused by indoor allergens such as dust mites, mold, fabrics, and animal dander.
By identifying specific allergens through serum testing, patients and healthcare providers can develop targeted strategies to manage allergic symptoms and improve overall quality of life.
If patients are exhibiting allergy symptoms or have tested positive for allergens like Aspergillus, Yeast, and Candida on food allergy and sensitivity tests, it may be prudent to extend testing to include environmental allergens on a panel such as the Environmental Allergy Test (88 Antigen IgE) By Infinite Allergy Labs.
This approach enables healthcare providers to comprehensively assess the patient's allergic sensitivities, as exposure to environmental allergens can exacerbate existing symptoms or contribute to overall allergic burden. Identifying and addressing environmental allergens alongside food sensitivities can lead to more effective management and treatment strategies tailored to the individual patient's needs, ultimately improving their quality of life.
Research supports the importance of comprehensive allergy testing to guide personalized treatment approaches and minimize allergic reactions. [24.]

IgE, an immunoglobulin subclass, plays a pivotal role in the body's allergic responses, particularly immediate hypersensitivity reactions triggered by exposure to foreign substances. These reactions can manifest as symptoms ranging from mild itching and hives to severe anaphylactic shock, depending on the individual's sensitivity and the allergen involved.
By measuring serum levels of IgE, our test helps identify potential allergic triggers, including food items and environmental antigens like pollen or pet dander, aiding in the diagnosis and management of allergic conditions.
Additionally, IgE-mediated reactions can also manifest with digestive symptoms such as nausea, vomiting, diarrhea, and abdominal pain, highlighting the importance of comprehensive testing for diagnosing allergic conditions involving the gastrointestinal tract. [12.]
Food sensitivity testing using IgG antibodies is employed by Infinite Allergy Labs in their FAST 88 Foods panel due to its potential clinical relevance in identifying delayed immune responses to specific food antigens.
While IgE-mediated food allergies typically provoke immediate hypersensitivity reactions, IgG-mediated responses are associated with delayed onset reactions, making them challenging to diagnose clinically. However, accumulating evidence suggests that IgG antibody testing for food sensitivities may shed light for clinicians. [6., 15., 19.]
Some studies indicate that IgG-mediated immune responses might contribute to the pathogenesis of gastrointestinal inflammation. [16.] By detecting IgG antibodies to specific food antigens, the FAST 88 Foods panel aims to identify potential triggers for immune-mediated reactions and provide insights into personalized dietary modifications to alleviate symptoms and improve overall health outcomes.
IgG4, a subtype of immunoglobulin G antibodies, plays a crucial role in modulating immune responses, particularly in the context of allergies. Research indicates that IgG4 antibodies can help neutralize allergic reactions orchestrated by IgE, thereby mitigating histamine responses and promoting immune tolerance to foods.
However, it's essential to maintain a balanced level of IgG4, as excessive amounts can paradoxically lead to increased inflammation and immune sensitization; increased IgG4 levels have been associated with allergies and with autoimmune conditions. For instance, elevated IgG4 levels have been implicated in conditions such as rheumatoid arthritis, myasthenia gravis, pemphigus vulgaris and thrombotic thrombocytopenic purpura. [8. 11.13.]
C3b/d (Complement Component 3) is a protein of the innate immune system that is activated by microorganisms in the absence of an antibody. The inclusion of complement proteins C3d and C3b in the Food Allergy and Sensitivity Testing (FAST 88 Foods: IgE, IgG4, IgG, C3b/d) by Infinite Allergy Labs provides a more comprehensive assessment of the immune response to dietary antigens.
Complement proteins play a crucial role in the immune cascade triggered by IgG-mediated reactions. Specifically, C3d and C3b are involved in the opsonization of immune complexes, facilitating their recognition and clearance by phagocytic cells; their role can increase the actions of IgG antibodies many times over.
By measuring levels of C3d and C3b alongside IgG antibodies against 88 common foods, this test offers valuable insights into the inflammatory response associated with food sensitivities.
Complement activation, particularly through the C3d/C3b pathway, may contribute to the pathogenesis of various immune-mediated disorders, including food sensitivities and allergic reactions. [26.]
IgE serum testing for allergens offers a comprehensive approach to identify specific allergens triggering allergic reactions in individuals. By testing for both seasonal and perennial allergens, healthcare providers can gain valuable insights into the patient's allergic sensitivities throughout the year.
Seasonal allergens, such as pollen from trees, grasses, and weeds, typically cause allergic symptoms during specific times of the year. In contrast, perennial allergens, including dust mites, pet dander, and mold, can trigger symptoms year-round. Differentiating between seasonal and perennial allergens allows for targeted treatment and management strategies tailored to the patient's specific sensitivities and environmental exposures.
For instance, while seasonal allergies may require seasonal avoidance measures or short-term medication use, perennial allergies necessitate ongoing allergen avoidance strategies and long-term management plans to address chronic health problems caused by perennial allergen exposure.
Testing for both food and environmental allergens enables healthcare providers to comprehensively assess the patient's allergic sensitivities, as exposure to environmental allergens can exacerbate existing symptoms or contribute to overall allergic burden.
Identifying and addressing environmental allergens alongside food sensitivities can lead to more effective management and treatment strategies tailored to the individual patient's needs, ultimately improving their quality of life. [24.]
Testing for IgE-mediated immune responses to molds, such as through the 88 Antigen IgE Environmental Panel, provides valuable clinical information about a patient's immediate hypersensitivity to specific mold allergens. Serum IgE has been correlated with IgE-mediated sensitization and inflammatory markers in response to mold exposure, making serum IgE a reliable marker for immune response to mold exposure. [7.]
This type of testing helps identify individuals who are sensitized to molds and at risk of developing allergic reactions upon exposure. By pinpointing the specific molds triggering allergic responses, healthcare providers can tailor treatment strategies, such as avoidance measures or allergen immunotherapy, to effectively manage symptoms and improve patient outcomes.
In contrast, urine mycotoxin testing aims to detect mycotoxins, toxic substances produced by molds, in the body. [23.] While urine mycotoxin testing may provide insights into mold exposure, it has limitations in assessing allergic sensitization and immediate immune responses. Furthermore, the clinical relevance and interpretation of mycotoxin levels in urine remain debated within the medical community.
Therefore, for evaluating IgE-mediated immune responses to molds and guiding allergy management, testing for mold-specific IgE antibodies is a more established and clinically relevant approach.
