Key Market Trends
-
Eco-friendly Immunoassays – Sustainability is gaining importance in diagnostics. Companies are transitioning from conventional plastics to biodegradable or recyclable materials in assay plates to reduce environmental impact. For example, Abbott announced in 2025 a roadmap to minimize single-use plastics in diagnostic kits.
-
Digital Integration & AI – Immunoassay systems are increasingly connected to cloud platforms and powered by AI analytics, enabling real-time monitoring, predictive insights, and seamless integration with electronic medical records (EMRs). Roche Diagnostics introduced AI-enabled analyzers in 2025 to improve throughput and digital connectivity.
-
Automation & High-Throughput Testing – Automated immunoassay analyzers are gaining traction in hospitals and large laboratories, enhancing efficiency, reproducibility, and patient outcomes.
-
Point-of-Care Testing (POCT) – Rising demand for rapid bedside diagnostics is driving the development of portable and user-friendly immunoassays, especially for infectious disease detection.
-
Non-invasive Specimens – While blood remains the primary sample, saliva and urine-based immunoassays are expanding, particularly in home-based or outpatient testing, improving patient convenience.
