What Is Covered Under Immunoassay Market?

Immunoassay is a bioanalytical test that employs antibody attachment to antigens to detect and quantify specific chemicals. Diseases can be diagnosed using immunoassays. Furthermore, information from test findings concerning an illness may be used to establish a course of therapy. This technique relies primarily on a competitive binding response for a finite number of receptors on an extremely specific anti-analyte antibody between a set quantity of labeled versions of an analyte and a substantial portion of an unmarked sample analyte. The main immunoassay product types are reagents and kits, analyzers or instruments, and software and services. A reagent is a material or product that can accelerate a reaction and is utilized in the majority of commonly used tests. The various specimens are blood, saliva, urine, and others applied to therapeutic drug monitoring, oncology, cardiology, endocrinology, infectious disease testing, autoimmune diseases and others. The end users are research and academic laboratories, home care settings, pharmaceutical and biotechnology companies and CROs, blood banks, hospitals and clinics, and clinical laboratories.

What Is The Immunoassay Market Growth Forecast?

The immunoassay market size is expected to see strong growth in the next few years. It will grow to $52.83 billion in 2030 at a compound annual growth rate (CAGR) of 7.2%. The growth in the forecast period can be attributed to increasing demand for rapid diagnostics, rising investments in personalized medicine, expansion of decentralized testing models, growing adoption of digital laboratory workflows, increasing focus on companion diagnostics. Major trends in the forecast period include increasing adoption of high-sensitivity immunoassay kits, rising use of automated immunoassay analyzers, growing demand for point-of-care immunoassay testing, expansion of multiplex immunoassay platforms, enhanced integration of data management software.

What Is The Driver Of The Immunoassay Market?

The increasing numbers of infectious and chronic illnesses is expected to propel the growth of the immunoassay market going forward. Infectious and chronic illnesses refer to diseases caused by pathogens or long-term medical conditions that require ongoing monitoring, diagnosis, and management. Infectious and chronic illnesses are rising due to greater exposure to environmental pollutants, which weaken immunity and increase susceptibility to disease. The immunoassay market is witnessing increased demand as the rapid expansion of infectious and chronic illnesses pushes companies to adopt advanced diagnostic tools that enable early detection, disease surveillance, and accurate clinical decision-making. For instance, in June 2025, according to the UK Health Security Agency (UKHSA), a United Kingdom–based government public health agency, the number of reported Campylobacter cases in England increased from 60,055 in 2023 to 70,352 cases in 2024, reflecting a rise of 10,297 cases (17.1%) and an increase in the reporting rate from 104.1 to 121.9 per 100,000 population. Therefore, the increasing numbers of infectious and chronic illnesses is driving the demand for the immunoassay industry.
