Immunoassay Market Key Success Factors and Forecast to 2033

Immunoassay Market Overview

Immunoassays are biochemical tests that leverage the specificity of antigen–antibody interactions to detect and quantify molecules in biological samples. Widely used in diagnostics, drug monitoring, and research, they play a critical role in identifying infectious diseases, autoimmune conditions, cancer markers, and cardiovascular disorders. The market’s importance lies in its ability to provide rapid, sensitive, and accurate diagnostic results, making immunoassays indispensable in clinical decision-making, pharmaceutical R&D, and disease surveillance.

Market Size & Growth Rate

According to Straits Research, the global immunoassay market size was estimated at USD 28.29 billion in 2025 and is projected to grow from USD 29.52 billion in 2026 to USD 42.43 billion by 2034, advancing at a CAGR of 4.64% during 2026–2034.

Key Drivers of Growth

The immunoassay market is driven by several factors. The rising global burden of infectious diseases, including HIV, hepatitis, and emerging viral outbreaks, has fueled the demand for rapid and reliable diagnostic solutions. Advances in biotechnology and automation have improved test sensitivity, throughput, and turnaround times, making immunoassays central to clinical laboratories. The increasing prevalence of chronic diseases, such as cancer and cardiovascular disorders, has further accelerated demand for biomarker-based testing. Additionally, growth in personalized medicine and companion diagnostics is expanding the use of immunoassays in tailoring treatments. Pharmaceutical and biotech companies rely on immunoassay technologies for therapeutic drug monitoring and clinical trials, while point-of-care testing is gaining traction due to its convenience and patient-centered approach.
