The Singleplex Immunoassay industry trends show renewed momentum as labs seek cost-efficient, high-specificity alternatives to multiplex panels. Over the past 18 months, Thermo Fisher’s $1.6 bn buy-out of Mesa Biotech transferred portable PCR-grade singleplex readers to its point-of-care line, while QIAGEN quietly acquired the Australian start-up Stat-Dx to integrate chemiluminescent singleplex cartridges into QIAstat-Dx firmware. Regulatory tailwinds accelerated adoption: the FDA’s 2023 reclassification of certain chemiluminescent cytokine assays from Class III to II cut approval timelines by nearly 40 %, prompting Eurofins to launch a 96-well IL-6 kit aimed at long-COVID monitoring. On the funding front, Siloam Biosciences closed a $42 M Series C to scale its nanoplate singleplex platform across Asian hospitals, and Boditech (Korea) opened a US CLIA hub in Irvine, CA, betting on decentralized testing demand. Meanwhile, enterprise procurement is shifting from bulk reagent tenders to modular pay-per-test contracts, favoring vendors that bundle cloud-based QC analytics with each immunoassay kit.
