Immunosensors Market to Reach USD 29.0 Billion by 2032, Growing at 4.58% CAGR | Rise in Infectious Diseases and Point-of-Care Testing Fuels Demand

The global Immunosensors Market is projected to grow from USD 20.27 billion in 2024 to USD 29.0 billion by 2032, reflecting a steady CAGR of 4.58%. Growth is driven by rising infectious disease prevalence, demand for rapid diagnostics, and advances in biosensor technology.
Published 20 July 2025

The Immunosensors Market is witnessing significant expansion as healthcare shifts toward faster, more accurate, and minimally invasive diagnostic solutions. Immunosensors, which detect specific biomolecules through antigen-antibody interactions, are essential in diagnostics, particularly for infectious diseases, cancer markers, and autoimmune disorders.

In 2024, the market is expected to be worth USD 20.27 billion, and by 2032, it is projected to hit USD 29.0 billion, growing at a compound annual growth rate (CAGR) of 4.58%. Key growth enablers include innovations in biosensor design, expansion in point-of-care testing (POCT), and rising investments in personalized medicine.
