Introduction
The Infectious Disease Diagnostics Market has been valued at USD 25.5 billion in 2024 and is projected to grow steadily at a compound annual growth rate (CAGR) of 2.75%, reaching USD 33.46 billion by 2034. With the rising burden of infectious diseases such as tuberculosis, HIV, influenza, hepatitis, and emerging pathogens, the demand for accurate and timely diagnostics has never been greater.
Diagnostics form the backbone of effective disease management by enabling early detection, timely treatment, and outbreak control. Increasing global focus on point-of-care testing, molecular diagnostics, and rapid diagnostic tests is accelerating adoption in clinical laboratories, hospitals, and decentralized healthcare settings.
Market Dynamics
Key Growth Drivers
- Rising Prevalence of Infectious Diseases
Infectious diseases remain a leading cause of mortality worldwide, particularly in low- and middle-income countries. Diagnostic tools are critical for disease surveillance, especially during outbreaks and pandemics. - Technological Advancements
Innovations in molecular diagnostics, next-generation sequencing, and microfluidics are enabling faster, more accurate detection of pathogens. Multiplex testing panels are now capable of identifying multiple infections from a single sample. - Growing Point-of-Care Testing
