Applications Insights

Based on application, the Alzheimer’s disease segment led the market with the largest revenue share of 35.6% in 2025 and is expected to dominate the market over the forecast period due to a rise in the prevalence of the disease and increasing awareness for early diagnosis and timely treatment. In addition, Labcorp's launch of the pTau217 test in 2024 represents a major advancement in Alzheimer's disease diagnostics. This biomarker, a crucial indicator of tau pathology, enhances early detection and disease monitoring, particularly in patients undergoing anti-amyloid therapy. Given that Alzheimer's affects 6.7 million Americans-a number projected to reach 13.8 million by 2060-the demand for accurate, minimally invasive testing is growing. This test complements Labcorp's existing biomarker portfolio, which includes the beta-amyloid 42/40 ratio, neurofilament light chain (NfL), and the ATN Profile-a combined panel assessing Alzheimer’s-related pathologies. The introduction of pTau217 provides physicians and biopharma partners with a powerful new tool for clinical trials, early intervention, and treatment monitoring, marking a significant step forward in neurodegenerative disease diagnostics.

Moreover, the Parkinson’s disease segment is also expected to grow fastest during the forecast period. Increasing R&D activities in biomarkers may offer new opportunities for Parkinson’s therapeutics. For instance, Merck and The Michael J. Fox Foundation (MJFF) are advancing Parkinson’s disease (PD) research with the SMCxPRO® immunoassay technology, enabling the detection of pS65 ubiquitin (pS65-Ub), a biomarker linked to cell dysfunction. With MJFF’s support, this technology is now available to the scientific community, helping track therapeutic responses to PD progression. Since 60-80% of nerve cells are already impaired when motor symptoms appear, detecting early dysfunction is crucial. The SMCxPRO platform allows researchers to measure low biomarker concentrations, enhancing diagnostics, patient stratification, and therapy development. Given that PD affects 10 million people globally, with cases projected to reach 20 million by 2050, this collaboration aims to develop disease-modifying treatments, as current therapies only address symptoms without slowing progression.

Type Insights

Based on type, the proteomic segment led the market with the largest revenue share of 30.5% in 2025. ​Proteomic biomarkers are increasingly pivotal in the market, especially for neurodegenerative diseases like amyotrophic lateral sclerosis (ALS) and Parkinson's disease (PD). These biomarkers facilitate early diagnosis and monitor disease progression by identifying specific protein alterations associated with neuronal degeneration. For instance, in ALS, proteomic analyses have revealed changes in proteins such as TDP-43, accumulating abnormally in affected neurons. Similarly, in PD, alterations in α-synuclein and its post-translational modifications have been identified, providing insights into disease mechanisms and potential therapeutic targets. Technological advancements in mass spectrometry and bioinformatics have enhanced the detection and quantification of these protein changes in biological samples like cerebrospinal fluid and plasma, driving the adoption of proteomic biomarkers in clinical and research settings. The growing prevalence of neurodegenerative disorders and the demand for personalized medicine further propel the integration of proteomic biomarkers into neurology.

The others segment which includes transcriptomic and phenomicis, is anticipated to witness significant growth over the forecast period. Advancements in multi-omics technologies fuel this expansion, the growing need for personalized medicine, and the increasing prevalence of neurodegenerative diseases. Transcriptomic biomarkers analyze RNA expression levels to identify gene activity associated with neurological disorders. For instance, studies have found that altered RNA expression patterns in blood and cerebrospinal fluid (CSF) can serve as early indicators of Alzheimer’s disease and Parkinson’s disease. A notable example is the identification of specific microRNAs (miRNAs) that differentiate Parkinson’s patients from healthy individuals, offering a non-invasive diagnostic tool. Phenomic biomarkers integrate biochemical, imaging, and behavioral data to comprehensively view neurological diseases. For example, diffusion tensor imaging (DTI)-based phenomic biomarkers help detect white matter changes in multiple sclerosis (MS) before clinical symptoms appear-similarly, phenomic profiling of metabolic alterations in CSF aids in distinguishing Alzheimer’s disease from other dementias. These biomarkers drive innovation in neurological research, supporting early diagnosis, treatment response monitoring, and the development of targeted therapies.

End Use Insights

Based on end-use, the research organizations and others segment led the market with the largest revenue share of 43.5% in 2025, driven by increasing investment in neurodegenerative disease drug development and the demand for highly sensitive biomarker assays. These companies are crucial in advancing biomarker research to support diagnostics and therapeutic interventions for conditions such as Alzheimer's, Parkinson’s, and ALS.
