The global immunoassay for neurological biomarkers market size was estimated at USD 1.08 billion in 2025 and is projected to reach USD 2.12 billion by 2033, growing at a CAGR of 8.91% from 2026 to 2033. Growth is supported by the rising prevalence of neurodegenerative diseases, increasing demand for early diagnostics, wider adoption of minimally invasive blood-based testing, and advancements in high-sensitivity immunoassays.
Furthermore, the expanding use of neurological biomarkers in drug development and precision medicine. The growing demand for early diagnosis of neurological disorders is significantly supporting the immunoassay for neurological biomarkers market, as early-stage detection improves treatment outcomes and enables timely therapeutic intervention. Neurological diseases such as Alzheimer's often remain undiagnosed in early stages, creating a strong need for accessible diagnostic tools. For instance, in October 2025, F. Hoffmann-La Roche received U.S. FDA clearance for its Elecsys pTau181 blood-based immunoassay, designed to aid in the early detection of Alzheimer's disease in clinical and primary care settings. These tests help identify patients at earlier stages, improving referral efficiency, reducing diagnostic delays, and thereby increasing demand for immunoassay-based biomarker testing across healthcare systems.
The transition toward minimally invasive blood-based testing is accelerating the clinical adoption of immunoassays, as these methods offer improved patient compliance, reduced procedural risks, and greater scalability than cerebrospinal fluid (CSF) testing and imaging techniques. Blood-based immunoassays enable routine testing in primary care and laboratory settings, expanding access to neurological diagnostics. Technologies such as high-sensitivity digital immunoassays (e.g., Simoa platforms) enable the detection of low-abundance biomarkers, such as pTau217 and neurofilament light chain, with high diagnostic accuracy. For instance, in May 2025, Fujirebio received U.S. FDA clearance for its Lumipulse G pTau217/B-Amyloid 1-42 plasma ratio test, a blood-based immunoassay designed to detect Alzheimer's pathology. These advancements enhance analytical sensitivity, reproducibility, and throughput, supporting large-scale clinical deployment and broader market adoption.
The increasing integration of neurological biomarkers into drug development and precision medicine is supporting the growth of the immunoassays for neurological biomarkers industry, as biomarkers are critical for patient stratification, treatment monitoring, and clinical trial endpoint evaluation. The development of disease-modifying therapies for Alzheimer's disease has intensified the need for accurate biomarker-based diagnostics to identify eligible patients at early stages. This growing reliance on biomarker-driven approaches is enhancing the clinical utility of immunoassays and reinforcing their role in advancing personalized treatment strategies and improving outcomes in neurological care.
