US Food Allergy Diagnosis and Treatment Market Overview
The US Food Allergy Diagnosis and Treatment market is experiencing significant growth due to the rising prevalence of food allergies, increasing awareness among consumers and healthcare providers, and advancements in diagnostic and therapeutic technologies. Food allergies affect both children and adults, with millions of Americans suffering from mild to life-threatening allergic reactions triggered by common allergens such as peanuts, shellfish, dairy, eggs, soy, and wheat. The growing public health concern around food allergies has created a strong demand for early diagnosis and effective treatment options, driving substantial expansion within the market.
The market encompasses a wide range of diagnostic tests and treatment approaches aimed at identifying allergens and managing symptoms. Diagnostic solutions such as skin prick tests, specific IgE blood tests, and oral food challenges are widely used across allergy clinics and hospitals. In parallel, treatment options include emergency medications like epinephrine auto-injectors, antihistamines, and long-term therapies such as oral immunotherapy (OIT) and biologics. With advancements in biotechnology, the landscape of food allergy treatment is evolving rapidly, introducing new modalities aimed at achieving sustained tolerance rather than merely managing symptoms.
The US Food Allergy Diagnosis and Treatment market is projected to grow at a strong CAGR in the coming years, driven by increasing incidence rates, evolving consumer lifestyles, and supportive regulatory developments. Factors such as early allergen exposure, urban living environments, and changes in the human microbiome have been associated with the rise in food allergy cases. The demand for personalized and precise allergy diagnosis and treatment is prompting healthcare providers to adopt more sophisticated tools and techniques.
The market can be segmented based on diagnosis type, treatment type, end user, and allergen type. In terms of diagnosis, skin prick tests remain the most widely used method due to their cost-effectiveness and rapid results. However, specific IgE blood tests are gaining popularity, particularly in situations where skin testing is not feasible. Oral food challenges are considered the gold standard for confirming allergies, especially in cases with inconclusive results from initial screenings. The adoption of component-resolved diagnostics (CRD) is also increasing, as it offers a more detailed analysis of allergen sensitivity at the molecular level.
When it comes to treatment, the market is categorized into emergency treatment, long-term immunotherapy, and biologics. Epinephrine auto-injectors such as EpiPen dominate the emergency treatment segment, with increasing focus on improving accessibility and affordability. Oral immunotherapy (OIT), which involves gradually introducing allergens to desensitize the immune system, is becoming more accepted, especially for peanut and milk allergies. Recent FDA approvals of allergen-specific immunotherapy products have further validated this approach. Biologics, including monoclonal antibodies like omalizumab, are emerging as a promising class of drugs that target the immune pathways involved in allergic reactions.
The end-user segment includes hospitals, allergy clinics, diagnostic laboratories, and retail pharmacies. Allergy clinics and diagnostic labs hold a significant share due to the specialized nature of food allergy testing and treatment. Hospitals play a vital role in managing severe cases, especially anaphylaxis, while retail pharmacies contribute through the distribution of epinephrine injectors and antihistamines.
Several developments have shaped the industry landscape in recent years. One major trend is the integration of digital health tools in allergy management. Mobile apps and digital platforms are being used to track symptoms, manage food intake, and alert users about allergen-containing products. Digital therapeutics are also emerging to support behavioral aspects of allergy management in children and adults. Moreover, the COVID-19 pandemic has accelerated the adoption of telemedicine in allergy care, allowing for remote consultations and follow-up visits, which is especially beneficial for immunotherapy patients.
Another noteworthy development is the increasing role of genetic and epigenetic research in understanding food allergies. Research institutions in the US are exploring genetic predispositions and the role of gut microbiota in allergy development. These studies are expected to lead to more personalized approaches to diagnosis and treatment. Additionally, the regulatory environment in the US remains supportive of innovation in this space, with the FDA encouraging fast-track approvals and orphan drug designations for novel therapies targeting rare or severe allergic conditions.

Key companies operating in the US Food Allergy Diagnosis and Treatment market include pharmaceutical, biotechnology, and diagnostic firms. Aimmune Therapeutics, now part of Nestlé Health Science, has developed Palforzia, the first FDA-approved oral immunotherapy for peanut allergy. DBV Technologies is working on Viaskin, a skin patch for peanut allergy treatment, which is in advanced stages of clinical development. ALK-Abelló and Stallergenes Greer are leaders in allergy immunotherapy products and are investing in expanding their offerings in the US.
Diagnostic companies such as Thermo Fisher Scientific and Danaher Corporation provide a broad range of allergy testing solutions, including automated systems and high-precision assays. Thermo Fisher’s ImmunoCAP platform is widely used for specific IgE testing and continues to be a preferred choice among allergists. BioMérieux and Omega Diagnostics are also contributing to the allergy diagnostics market with innovative testing kits.
The key market drivers include the increasing incidence of food allergies, heightened consumer awareness, technological advancements in diagnostics and therapeutics, and favorable government policies. According to clinical estimates, food allergies affect around 8 percent of children and up to 10 percent of adults in the US. The growing burden of food allergy-related hospital visits and emergency room admissions is pushing both public health authorities and private players to invest more in preventive and long-term management strategies.
Consumer awareness campaigns by organizations and food regulatory bodies are leading to better understanding and early detection of food allergies. Initiatives such as clearer allergen labeling, school-based allergy management policies, and public availability of epinephrine have contributed to increased safety and awareness. Parents and caregivers are becoming more proactive in seeking early diagnosis and treatment for children with suspected allergies, boosting market demand.
Technological innovation is another major factor propelling market growth. Advanced molecular diagnostics, AI-powered diagnostic tools, and telehealth platforms are making allergy diagnosis more accessible and precise. Research into hypoallergenic food formulations and alternative proteins is also gaining attention, opening new avenues for dietary management of allergies.
Regionally, the market is highly developed across all major US regions. The Northeast and West Coast regions, which include states like New York, Massachusetts, and California, are leading in terms of research, healthcare infrastructure, and adoption of innovative treatments. These regions house several top hospitals, research centers, and biotech firms actively engaged in allergy-related R&D. The South and Midwest regions are experiencing rising awareness and improvements in allergy care access, supported by expanding healthcare networks and insurance coverage.
