North America Immunoassay Market Report

North America Immunoassay Market Size

The North America immunoassay market size was valued at USD 10.59 billion in 2025 and is estimated at USD 11.61 billion in 2026, projected to grow at a CAGR of 9.66% from 2026 to 2034 to reach USD 24.28 billion by 2034.

North America accounted for the largest share of the global market in 2024 owing to the increasing adoption of low-cost immunoassay instruments in research and clinical laboratories and the rising application of immunoassay techniques in cancer research.

The growing incidence of chronic and infectious diseases, advances in immunoassay technology, and increased acceptance of immunoassay products are majorly driving the market growth for immunoassay in the North American region during the forecast period. Chronic diseases such as diabetes, heart disease, and cancer are rising. In addition, infectious diseases such as SARS-CoV-2 (COVID-19), Dengue fever, Hepatitis B and C, HIV, Malaria, Tuberculosis, and others are spreading at an alarming rate. Immunoassay diagnosis has become a critical component in diagnosing many disorders. Immunoassay technology improves, resulting in faster results with improved efficacy, detection limits, sensitivity, and cost-effectiveness. The widespread use of fast tests and point-of-care testing for disease detection and drug and alcohol addiction has propelled the immunoassay market to new heights in this region. In addition, the growing investments from governmental and non-government organizations to conduct R&D in emerging markets promote the immunoassay market’s growth rate in North America.

Factors such as complicated assay techniques and immunoassay limitations could hamper the market growth in the North American region. The approval and commercialization of immunoassay consumables and equipment have been subject to strict regulations by regulatory bodies in this region. Furthermore, technological challenges faced by immunoassay kits and reagents, such as cross-reactivity of antibodies, narrow detection limits of accessible antibodies, lack of reimbursement programs and stringent storage requirements, false negatives, and others, stifle the North American immunoassay market's expansion.

REGIONAL ANALYSIS

During the forecast period, the North American region is estimated to occupy the most significant share of the worldwide market. The market growth of the North American region is majorly driven by the growing adoption of low-cost immunoassay equipment in research and clinical laboratories, rising immunoassay approaches in cancer research, and improving laboratory infrastructure; the North American immunoassay market had the most significant share in the global market in 2023. In addition, other significant factors propelling the regional market include rising R&D investment by government organizations and pharmaceutical corporations for disorders and diseases such as chronic ailments and diabetes.

The U.S. immunoassay market had the most significant share in the North American region in 2023. The dominating role of the U.S. in the North American region is anticipated to continue throughout the forecast period, and the U.S. market growth is mainly attributed to the growing prevalence of chronic diseases and infectious diseases, increasing geriatric population, the presence of well-developed healthcare infrastructure and growing penetration of medical technologies. In addition, the availability of technologically well-developed immunoassays is one of the other significant factors contributing to the growth of the U.S. market. On the other hand, the Canadian immunoassay market is anticipated to showcase a healthy CAGR during the forecast period, owing to the increasing R&D activities and growing usage of immunoassays.
