Allergy Diagnostics Market Size & Share 2025 - 2034

Allergy Diagnostics Market Size

The global allergy diagnostics market was valued at USD 5.6 billion in 2024. The market is expected to grow from USD 6.1 billion in 2025 to USD 13.4 billion in 2034, at a CAGR of 9.2%. The market growth is driven by the increasing use of molecular diagnostics and AI, expansion of at-home care and point-of-care testing, supportive government reimbursement policies, and growth in personalized therapies, especially immunotherapy and targeted allergy treatments.

The need for advanced diagnostic procedures continues to grow due to the rising cases of allergic conditions such as asthma, food allergies, allergic rhinitis, dermatitis, and others. The World Health Organization (WHO) reported that allergies affected nearly 40% of the world's population in 2023 and increased annually by 10-15%. Similarly, the Centers for Disease Control and Prevention (CDC) estimates showed that food allergies in the U.S. reached 32 million in 2022, including 5.6 million children.
 

Social and economic activities that change with climate change and pollution are common risk factors for rising allergies. The European Academy of Allergy and Clinical Immunology (EAACI) in 2023 reported that Allergic Rhinitis affects 24.6% of the European population, which grew by 4% since 2021. This increase has led to higher awareness of the condition among consumers and professionals, driving market growth. Additionally, non-facility based care is moving toward self-administered rapid allergy tests. At-home or point-of-care diagnostic kits are preferred because they are easy to use, give quick results, and reduce the burden on the healthcare system. Telemedicine appointments with allergy
 

 specialists help deliver services to distant regions, improve market access, and make remote healthcare easier, supporting growth in the coming years.
 

Allergy diagnostics includes all procedures that help identify specific allergens that cause allergic reactions in a person. These include skin and blood tests as well as challenge tests to check sensitivity to allergens such as pollen, dust, food, and pet hair, which help create treatment plans for the individual.
 

Allergy Diagnostics Market Trends

• The market is likely to expand with developments in artificial intelligence, at-home testing, and molecular testing for individual allergies. There is more allergy awareness and initiatives toward precision medicine which enhance techniques and methods to manage allergies.
   
• There is noteworthy transition to component-resolved diagnostics (CRD) at the molecular level, which alters how we detect allergens accurately. This will improve personalized allergy treatments while reducing wrong diagnoses. The use of microarray-based tests and next-generation sequencing (NGS) will also help the industry grow.
   
• Data pertaining to allergic reactions to certain foods demonstrates the gaps in diagnostic capabilities. Approximately 32 million people in the U.S. suffer from food allergies as stated by the CDC. Urban living, pollution, and climate change are primary drivers for the increase in cases of asthma, rhinitis, and food allergies and highlights the need for advanced technologies for testing.
   
• According to a study by the EAACI shows that one in three Europeans will have health complications stemming from allergies in 2024 and the global spending on allergy services has increased by 25% from 2021 to 2023, adding to the economic burden of allergies. The study also notes that allergy diagnosis methods are getting more advanced, which shows growing concerns about allergies worldwide.
   
• AI and machine learning algorithms are now used in allergy diagnosis to improve accuracy, speed, predictive analysis, and overall efficiency. The increased automation in skin prick and blood sample testing has improved productivity and accuracy in laboratories. This aids in the timely provision of results. Further, optimization AI diagnostic tools are expected to enhance the productivity of clinicians which is expected to drive growth in the entire market. 
   
• There is increasing investment aimed at providing reliable allergy testing where patients need it, which is also a driver of growth of the market. Development of handheld immunoassay devices and biosensors that would help patients depend less on central laboratories. In addition, remote consultations as well as interpretation of diagnostic tests are being incorporated into telemedicine, thereby extending healthcare access in rural and underserved regions.
   

Allergy Diagnostics Market Analysis

The market by products and services is segmented into services, consumables, and instruments. The services segment continues to dominate, securing a substantial market share valued at USD 2.8 billion in 2024.
 

• Due to the high inventory equipment costs and low in-house proficiency, numerous hospitals, clinics, and even small diagnostic centers are outsourcing their allergy testing to specialized laboratories. This increases the supply of allergy testing services, while simultaneously enhancing the structural peripheral diagnostic service providers.
   
• In addition, the growing implementation of telemedicine has enabled patients to have remote access to allergy consultations as well as diagnostic services. The utilization of telehealth services has sharply increased to 85% in 2022 from 75% in 2021, according to the American Medical Association, marking a significant rise.
   

Based on test type, the allergy diagnostics market is categorized into in vivo and in vitro. The in vivo segment held a dominant market share and accounted for USD 3.5 billion in 2024.
 

• In vivo techniques, like skin prick tests (SPT), intradermal tests, and many other in vivo test types, are known to be the most popular due to their effectiveness and timely results. These tests show immediate allergic responses that allow for multiple allergens to be diagnosed, such as pollen, dust mites, food, and even insect venom.
   
• In addition, the in vivo allergy testing is more affordable than the in vitro (blood-based) test and has proven to be especially useful in cost-sensitive markets. As per the median estimates, the in vivo skin prick testing reimbursement stands at 7-9 USD for the procedures, while in vitro blood tests command a fee of 15-20 USD (CMS, 2023). The NHS UK reported in 2022 that skin tests are about 60 percent cheaper than blood tests in their facilities.
   

Based on allergens, the allergy diagnostics market is categorized into inhaled allergens, food allergens, drug allergens, and other allergens. The inhaled allergens segment held a dominant market share and accounted for USD 2.8 billion in 2024.
 

• The sharp rise in allergic rhinitis, asthma, and chronic respiratory diseases is triggered by inhaled allergens such as pollen, mold spores, dust mites, and pet dander. As a result, there is an increasing need for thorough allergy diagnostics. The AAFA (Asthma and Allergy Foundation of America) reports that over 25 million individuals in the U.S. are asthmatic, with a large number of these cases made worse by environmental allergens.
   
• Also, in allergy tests using whole-allergen extracts, cross-reactivity may occur, causing wrong results. The use of CRD technology allows for better accuracy in identifying specific allergenic proteins from the inhaled matrix, which improves the diagnostics for pollen allergies and allergic asthma.
