According to a new report by Polaris Market Research, the global Molecular Infectious Disease Testing market was valued at USD 10.27 billion in 2025 and is projected to reach USD 28.02 billion by 2034, expanding at a CAGR of 11.80% over the forecast period. Growth is underpinned by the rising global burden of infectious disease, rapid technological advancement in PCR and sequencing platforms, and accelerating demand for point-of-care molecular diagnostics across hospitals, laboratories, and decentralized testing settings.
What Is Driving Molecular Infectious Disease Testing Market Growth?
Demand is climbing as healthcare systems prioritize rapid, highly sensitive nucleic-acid-based detection over slower traditional culture, antigen, and serology methods, pushing molecular infectious disease testing adoption across respiratory, gastrointestinal, and sexually transmitted disease categories. In April 2026, QuidelOrtho expanded its decentralized diagnostics footprint by acquiring LEX Diagnostics' rapid PCR technology, which received FDA approval and a CLIA waiver in February 2026 for multiplex detection of Influenza A, Influenza B, and COVID-19 in under ten minutes.
Polaris analysts note that sustained public and private funding — including BARDA and University Lab Partners' USD 10 million ReadyDetect competition launched in September 2025 to accelerate next-generation diagnostics through 2028 — positions the reagents & kits segment for the fastest growth through 2034, with laboratory tests remaining the largest revenue contributor.
Key Trends Shaping the Molecular Infectious Disease Testing Industry
Multiplex PCR and Syndromic Testing Panels
Panels capable of detecting numerous pathogens from a single sample — such as QIAGEN's CE-IVDR-approved QIAstat-Dx BCID GPF Plus AMR Panel, which identifies 20 pathogens and 10 antimicrobial-resistance markers from bloodstream infections in about an hour — represent a clear technology advancement improving diagnostic speed and efficiency.
Expansion of Point-of-Care Molecular Diagnostics
Decentralized testing is reshaping the regulatory landscape as healthcare providers seek rapid, accurate results outside centralized laboratories, improving treatment decisions in hospitals, clinics, and home-care settings alike.
AI-Enabled Pathogen Detection and Lab Automation
Machine learning is improving test accuracy by identifying patterns that manual analysis can miss, while AI-driven laboratory automation is strengthening the competitive landscape by increasing testing throughput and reducing turnaround time.
Market Segmentation: Breaking Down the Molecular Infectious Disease Testing Market
Polaris segments the molecular infectious disease testing market by product & service, type, test type, disease, technology, end user, and region, giving each buyer persona a citable, standalone data point.
By Disease
The sexually transmitted diseases segment led the market with a 22.8% share in 2025, driven by rising STI prevalence, expanding screening programs, and growing demand for early, accurate molecular diagnostic solutions, ahead of respiratory, gastrointestinal, and hospital-acquired infection categories.

By Product & Service
Reagents & kits are projected to post the fastest growth at a 10.6% CAGR through 2034, reflecting recurring demand for nucleic-acid extraction kits, PCR reagents, and pathogen-specific assay kits as testing volumes rise across centralized labs and point-of-care settings.
By Test Type
Laboratory tests held a 68.5% share in 2025 on the strength of high analytical accuracy and broad availability in centralized diagnostic labs, while point-of-care tests are expanding quickly as decentralized testing gains ground.
Regional Outlook: Where Is Molecular Infectious Disease Testing Growing Fastest?
North America led the market with a 41.9% share in 2025, supported by well-established healthcare infrastructure, favorable reimbursement policies, and the presence of leading diagnostic companies — CDC data cited in the report shows more than 2.4 million reported cases of syphilis, gonorrhea, and chlamydia in 2023 alone, reinforcing demand for rapid, accurate testing. Asia Pacific is projected to grow at the fastest CAGR of 10.2% through 2034, driven by expanding healthcare investment, growing laboratory infrastructure, and initiatives such as Sansure Biotech's 2022 collaboration with QuantuMDx on the portable Q-POC molecular diagnostic platform.
Competitive Landscape: Leading Molecular Infectious Disease Testing Companies
Key players profiled in the report include Roche Diagnostics, Thermo Fisher Scientific, Abbott Laboratories, and QIAGEN, who are focusing on multiplex PCR platform development, next-generation sequencing, and regulatory clearances to strengthen market position across the sexually-transmitted-disease and laboratory-test segments outlined above. QIAGEN's QIAstat-Dx syndromic testing system and Roche's broad in-vitro diagnostics portfolio illustrate the shift toward faster, more comprehensive pathogen panels. Additional participants such as bioMérieux, Bio-Rad Laboratories, Becton Dickinson, Hologic, Illumina, Danaher Corporation, Siemens Healthineers, Sysmex Corporation, and Bruker Corporation round out a competitive landscape built on R&D scale and global distribution reach.
