Regional Analysis
In 2023, North America led the global multiplex assay market, accounting for the highest revenue share of 38.6%. This dominance is attributed to the region’s strong focus on gene-editing technologies such as CRISPR, supported by substantial public funding. The National Institutes of Health (NIH) allocated approximately US$ 34.9 billion for extramural research grants in FY2023, with a significant portion directed toward CRISPR-Cas9-related projects.
The expanding number of clinical trials targeting cancer and genetic disorders further fuels the demand for multiplex assays. Additionally, regulatory clarity from the U.S. FDA concerning gene-edited therapies has boosted confidence among biotechnology companies, driving investments and product development in the region.
Meanwhile, the Asia Pacific region is expected to register the highest CAGR during the forecast period. Countries such as China, South Korea, and Japan are increasing their investments in biotechnology and genomic research. China’s R&D expenditure reached 2.54% of its GDP in 2022, reflecting strong government backing. Rising prevalence of genetic disorders and expanding international collaborations in gene-editing initiatives are likely to stimulate market growth. Overall, growing adoption of CRISPR-based technologies and expanding biotech infrastructure are expected to significantly drive the multiplex assay market in Asia Pacific.
Emerging Trends
- Digital PCR–Based Multiplexing: The adoption of digital PCR (dPCR) for multiplex assays has been accelerated by its capacity for absolute quantification without calibration curves. In this approach, samples are partitioned into thousands of micro-reactions, enabling sensitive detection of low-level targets and improved resistance to inhibitors. This trend has broadened applications in infectious disease diagnostics, where precise viral load measurements are critical for patient management and public health surveillance.
- Machine Learning–Enhanced Assay Design: Machine learning algorithms have been integrated with high-throughput multiplex platforms to optimize assay parameters and interpret complex amplification data. By training models on large datasets, assay performance metrics such as limit of detection and specificity are improved, and analytic time is reduced. This coupling of artificial intelligence with multiplex dPCR has demonstrated enhanced detection of antimicrobial-resistance genes and other critical biomarkers in clinical samples.
- Microfluidic Lab-on-a-Chip Devices: Microfluidic platforms are increasingly being used to miniaturize multiplex immunoassays for point-of-care testing. Capillary-driven chips that incorporate dry, antibody-coated beads allow the initial binding steps to occur at the time of sample collection, preserving target integrity and enabling shipment to central labs for analysis. Such devices have been shown to process multiple protein biomarkers from microliter-scale samples with high sensitivity and low reagent use.
- Bead-Based Multiplex Immunoassays: Bead-based platforms continue to gain traction for serological and immunological studies, as they allow simultaneous measurement of dozens of analytes in a single well. Their high-throughput capability has been leveraged for antibody avidity and titer assessments across multiple pathogens, reducing sample volume requirements and overall assay time. Comparative evaluations have confirmed concordance with single-target assays, supporting their use in both research and surveillance contexts.
- Expanded Respiratory Pathogen Panels: The scope of multiplex RT-PCR panels has been broadened to include simultaneous detection of SARS-CoV-2, influenza A/B, RSV, and other respiratory agents. This expansion supports efficient differential diagnosis during peak respiratory seasons and has been implemented in public health laboratories to conserve resources and accelerate reporting. Full concordance with individual FDA-approved assays has been demonstrated in multi-pathogen panels, underscoring their clinical reliability.
