What are biomarker-based immunoassays ?
Immunoassays based on biomarkers facilitate the early detection, monitoring, and targeted treatment of chronic diseases and age-related conditions. Advanced technology involving multiplex assays and AI-supported analysis enhances precision, productivity, and patient outcomes. Applications range from clinical diagnostics and research to preventive healthcare.
Government health programs, early detection funding, and precision medicine initiatives are driving market uptake. Chronic disease management programs and awareness campaigns are driving access to biomarker testing in hospitals and clinical laboratory settings.
How Biomarker-Based Immunoassays Work?
The testing process begins with gathering a biological sample from the patient. The biological sample can take the form of blood, serum, or saliva. Specific antibodies bind the marker of interest within the sample in this type of analysis. The reaction is detected by a measuring instrument. These tests enable medical practitioners to determine various diseases and the health status of patients.
Increasing healthcare spending, investments in diagnostic facilities, and training of lab staff are fueling market growth. Advanced healthcare economies are implementing cutting-edge immunoassay platforms, enhancing test effectiveness, lowering diagnosis times, and providing both clinical and economic advantages. In April 2025, Labcorp launched a novel pTau-217/Aβ42 blood test that satisfies performance requirements for the confirmation of amyloid pathology linked to Alzheimer's disease, enabling earlier and more precise diagnosis.

Drivers & Opportunities
Rising Global Prevalence of Chronic and Lifestyle Diseases: Growing incidence of chronic diseases, such as cancer, cardiovascular disease, and autoimmune disease, is driving the need for biomarker-based immunoassays. According to the World Health Organization (WHO), chronic disease is responsible for 75% of deaths worldwide, primarily cardiovascular disease, cancer, respiratory disease, and diabetes, with premature deaths primarily occurring in low and middle-income nations. Detection and precise monitoring are essential for successful control of disease, fueling hospital, laboratory, and research facility uptake of sophisticated immunoassay technologies.
Aging Population Drives Demand for Disease Monitoring: Growing proportion of older individuals is driving demand for chronic disease monitoring and regular biomarker testing. The WHO states that by 2030, one in every six individuals globally projected to be 60 or older, with the world population in this group growing from 1 billion in 2020 to 1.4 billion, and expected to be 2.1 billion by 2050; those 80 and older are forecasted to triple, hitting 426 million by 2050. Older persons are more vulnerable to age and chronic disease, which sustains demand for accurate diagnostics to enable preventive care, customized treatment, and continuing patient management.
