Antibody testing is used to verify if an antibody can bind to the selected target and does not react with other molecules. This is also a verification step for the research and documentation for the development of targeted drugs and therapies. The main goal of this test is to verify a specific antibody for diagnosing and treating the patient.

An increasing shift toward custom and personalized protein therapeutics boosts the industry expansion. Such treatments involve the application of monoclonal antibodies tailored to the patient's individual genetic and disease profile. This growing trend drives the demand for more advanced antibody validation services. Another important driver is the increasing concentration on applied research and the development of strategic collaborations. Such collaborations between research organizations and the industry create a continuous demand for antibodies of high quality and reliability. The National Institutes of Health (NIH) supports biomedical research, and part of the funding is allocated to the development of antibodies, which drives the need for specificity testing.

Drivers and Trends

Rising Prevalence of Chronic and Infectious Diseases: In the U.S., there is an increase in the number of chronic and infectious disease cases. Conditions such as cancer and certain autoimmune diseases often require therapeutic solutions that are frequently based on antibodies. New drug developments for such conditions depend on reliable and accurate antibody specificity testing. This process determines the effectiveness and the safety of new treatments for the patients.

The Centers for Disease Control and Prevention (CDC), in its "Trends in Multiple Chronic Conditions Among US Adults, By Life Stage, Behavioral Risk Factor Surveillance System, 2013-2023" report from 2025, noted that in 2023, about 194 million adults in the U.S. had one or more chronic conditions. This growing number of people affected by long-term illnesses increases the demand for new treatments and the development of new antibody-based drugs. The need to check these new drugs for accuracy and effectiveness drives the market growth.

Increased Funding and Research Initiatives: Growing investments in research and development boost the industry expansion. Antibody-based targeted therapies are receiving more funding from the government and educational institutions. This funding assists in the advancement of basic research and clinical trials, which require robust testing of antibody specificity.

A 2024 report titled "Cancer Facts & Figures" from a government-adjacent organization shows that cancer is the second leading cause of death in the U.S. The need for new treatments for such a high-impact disease leads to more investment in research. The National Cancer Institute (NCI), a part of the NIH, provides significant funding for cancer research, including for the development of new immunotherapies. This ongoing support for R&D in areas with high medical need directly drives the need for antibody specificity testing to validate research and therapeutic candidates.
