Infectious disease testing encompasses molecular diagnostics, immunoassays, and rapid antigen tests detecting bacterial, viral, fungal, and parasitic pathogens enabling early intervention. The infectious disease testing market size was valued at USD 28 billion in 2025 and is projected to grow from USD 30 billion in 2026 to USD 60 billion by 2034 at a CAGR of 7% during the forecast period (2026-2034), as per Straits Research Analysis.

Market Drivers

Rising antimicrobial resistance affecting 1.27 million deaths annually necessitates rapid diagnostics identifying causative pathogens guiding targeted therapies. Global health security initiatives fund surveillance networks monitoring influenza, mpox, and emerging coronaviruses requiring scalable testing infrastructure.

Point-of-care molecular platforms deliver results within 30 minutes supporting outbreak containment and reducing hospital transmission rates by 40%.

Market Challenges

High costs of next-generation sequencing and mass spectrometry limit adoption in resource-constrained settings while complex sample processing requires skilled technicians. False positive/negative rates in low-prevalence scenarios trigger unnecessary treatments or missed diagnoses. 

Regulatory harmonization gaps across FDA, EMA, and WHO delay multiplex panel approvals for comprehensive respiratory panels.
