Sepsis Diagnostics Market Projected to Reach USD 1,255.14 Million by 2034, at a CAGR of 7.0%

The global sepsis diagnostics market was valued at USD 639.55 million in 2024 and is projected to reach USD 1,255.14 million by 2034. The market is expected to grow at a compound annual growth rate (CAGR) of 7.0% from 2025 to 2034, rising from an estimated USD 682.72 million in 2025.

Key Market Trends

Surge in Point-of-Care Testing (POCT)

Point-of-care diagnostics are becoming a cornerstone of sepsis management, especially in emergency and intensive care units. Modern POC systems now offer results in under 30 minutes, enabling clinicians to initiate treatment promptly. The trend toward bedside testing is particularly strong in high-income countries, where cost is less of a barrier.

Rise of Molecular Diagnostic Technologies

Molecular platforms—especially PCR-based assays and next-generation sequencing (NGS)—are gaining significant traction. These technologies can detect bacterial and viral pathogens and their antimicrobial resistance profiles within a few hours, a considerable improvement over traditional blood cultures that may take 24–72 hours.

Biomarker Panel Expansion

Traditionally, markers like procalcitonin (PCT) and C-reactive protein (CRP) have been used in sepsis diagnostics. However, the market is witnessing a shift toward multi-marker panels including interleukins, soluble triggering receptor expressed on myeloid cells-1 (sTREM-1), lactate, and cell-free DNA (cfDNA) for enhanced specificity and sensitivity.

Integration of Artificial Intelligence (AI)

AI and machine learning are transforming sepsis diagnostics by enabling real-time analysis of electronic health record (EHR) data, vital signs, and laboratory results to predict the onset of sepsis. Predictive models and clinical decision support systems are increasingly being integrated into hospital workflows, especially in North America and Europe.

Market Overview

The global sepsis diagnostics market has emerged as a critical focal point within the broader infectious disease and critical care diagnostics landscape, driven by the urgent need for early and accurate identification of sepsis—a systemic inflammatory response to infection that remains one of the leading causes of in-hospital mortality worldwide.

Sepsis continues to impose a substantial burden on global health systems, with epidemiological data indicating that it affects more than 49 million people annually, resulting in nearly 11 million deaths—approximately 20% of all global fatalities. In the United States alone, sepsis accounts for over $24 billion in annual hospital costs, highlighting its significant economic impact alongside its clinical severity. These alarming figures have prompted widespread adoption of standardized sepsis protocols such as the Centers for Disease Control and Prevention’s (CDC) “Sepsis Care Bundle” and the Surviving Sepsis Campaign guidelines, which emphasize rapid diagnosis and timely antimicrobial administration. As a result, demand for advanced diagnostic tools capable of identifying pathogens and guiding targeted therapy has surged across both developed and emerging markets.
